This engine is designed to have a high level of drivability, or street manners. Cams #3 and #4 are our favorites for offering exceptional low end and mid range performance plus max drivability without needing to deepen final gearing or the need for a high stall speed torque converter.
If you choose to go with the Hurricane single plane intake and the first choice cam with 1.6 rockers, it will bring the hp numbers up to approx. 530. We do not recommend the single plane intake combined with cam choice 1 on any car that is over approximately 3400
Please read the cam info provided below on the four cam choices before purchasing this engine. It is very important that you choose the correct cam and intake for your car and its intended purpose.
Here are a few good reasons why we think the 377 engine is a better choice than the 350 engine.
1. The 377 will accelerate most medium to heavy cars dramatically quicker than the common 350's on the market. The main difference between a 377 and the 350 is that the 377 has a huge increase in overall power and torque. The difference is so dramatic that you would estimate the engine to have a much higher horsepower rating than it actually has. If you're not familiar with the 377 engine, do an internet search on SBC 377 vs 350 or 383's, and you will be convinced of the difference. There is no inherent weakness in the 377 engine when using a Dart high performance block. These engines are built to last. All parts used have much higher hp ratings than this engine is producing.
2. The exhaust note that this engine produces is much deeper than that of any of the smaller cubic inch engines on the market. The difference is dramatic to say the least.
3. This engine can be installed in medium to heavier cars without killing acceleration, having to deepen the final gear, and needing a huge stall converter. This engine will accelerate a 3600 lb or heavier car much better than the 350.
4. Very low maintenance, decent drivability, yet costing only slightly more than building a 350 street rod engine. Horsepower will vary, depending on cam, carb and intake choice. You have up to four different cams to choose from, and two styles of intake manifolds plus two rocker ratios.
5. Longevity, reliability and low maintenance. You don't have to turn the engine to a critical rpm range to produce its max hp output. There is nothing unsafe about running an engine that's as well built as this up to approx. 6,300 rpm. Our NKB aluminum heads use very high quality hardware. The new Dart Super High Performance block would be indestructible if built to the power rating of this engine. The Wiseco Racing pistons are rated at 800+hp. The protection against detonation is at its highest with these type pistons.
6. Should you ever decide to sell your car, the resale value of a street rod with a 377 engine is very desirable compared to those running 350's No 350 can be built up to the level of a 377 while running pump gas with the same compression.
We do a full test run on every engine we build on a test mule. The engine is run for two intervals of 15 minutes each, and every possible issue is addressed. When you install the engine, you must verify that the timing is set at the correct value, and the fuel to air ratio must be verified. We also include an engine stand like the one pictured, wheels included, and an engine lift plate.
The build sheet is as follows:
Pictured below is the new Dart SHP block. This block is the absolute ultimate in quality, durability, and value.
Dart SHP block, splayed caps
The block is bored to size with our new Centroid touch probe machine. Few machine shops have a machine of this accuracy.
We also deck the blocks to an RA finish of approx. 15 or better. The decking procedure is also done by our Centroid CNC machine.
We often find many brand new blocks to have a sloping deck of up to 4 thous. When we're finished decking the block, it is within approx. .001 accuracy from end to end. Many machine shops fail to catch this as the machinery they use does not allow for such accuracy.
We then plate hone the block with our new Sunnen SV10 diamond hone machine. This is also a very advanced machine that hones the block with a finish unlike conventional machines.
The final step is to clean the block in our high pressure block washer.

WISECO FULLY FORGED PISTONS, RATED AT 800+ HP. WISECO PISTONS ARE 100% MANUFACTURED IN THE USA. THEY ARE ONE OF THE HIGHEST RATED PISTON BUILDERS IN THE COUNTRY.
The Wiseco fully forged pistons are rated very high in the street/strip performance industry. They offer several price levels of pistons, starting with the Pro-Tru Street version made with 4032 forged alloy. The next level up would be the Professional series that are much more expensive and made from 2618 aircraft alloy.
Our custom made Wiseco pistons are very close in comparison to the Professional series as they are made using the 2618 aircraft alloy and have fully machined crowns.
Our Wiseco Forged pistons are custom designed with an increase in compression height. This has many advantages. Here are a few facts about compression height and deck height.
Our custom made Wiseco pistons have a compression height that is .015 taller than nearly all catalog pistons on the market. We find this to be a very valuable feature.
Another good feature about our pistons having a taller compression height is that the ring land above the top ring is much stronger by being .015 thicker. When pistons encounter the effects of detonation, it is not uncommon to see pistons with the ring land above the top ring broken off. The thicker ring land also makes a better heat sink.
You may have noticed that our Wiseco custom made forged pistons are referred to as Racing Pistons on the package. This does not mean that the pistons are for racing only. This is a generic term, referring to their ability to be used in high performance applications as well as for street rod use. These pistons are perfectly designed for use on the street, as well as for medium to upper level drag racing.
Our custom made Wiseco forged pistons are made from 2618 aircraft alloy. We find this alloy to be much more suitable for high performance engines than the common 4032 forged alloy. You will usually see the higher end pistons on the market using 2618 aircraft alloy.
Why go with 2618 forged pistons? If you encounter certain tuning issues, detonation is highly probable, and its effects can cause severe damage to your engine. The 2618 forged piston is able to withstand the damaging effects from detonation to a higher degree than the lower cost 4032 forged pistons, especially non-forged hypereutectic pistons such as Speed Pro or Keith Black, and many others.
We have built approximately 3500 engines using the Wiseco pistons. The engines have been for street rod and strip use. We have seen no problems, nor have there been any complaints. They are an excellent product in every respect.
These pistons are also suitable for use with nitrous or blower setups.
The pictures below are file photos of our Wiseco pistons. Flash glare on the piston top seems to have enhanced the milling marks. These are hardly visible with the naked eye.

HASTINGS HIGH PERFORMANCE MOLY RINGS
The picture below is a generic file photo of a Scat crankshaft.
Some of the benefits of the Scat crankshaft:
The material used in this crankshaft is manufactured from an exclusive Space Age material that was designed for high strength and fatigue resistance. The Scat cranks are the best value you will ever find. The Scat crankshafts are the best way to build a strong bottom end for, street rods, dirt and circle track racing, and drag strip racing.
We now use the Clevite bearings in our engines.
Our choice of rods are the SCAT COMPETITION SERIES rods with ARP-8740 cap screws.
The Scat Pro-Comp extreme duty I-beam rods should not be mistaken for ProComp rods. These rods are made exclusively by Scat, and have nothing to do with the ProComp company. The critical sizing and installation of the ARP cap screws is performed on a Sunnen machine in the USA by Scat Industries. These rods are excellent for those wanting the extra security offered by a rod with 7/16 ARP cap screws.
Take notice of the design of these rods. They are far superior to conventional style I-beam rods. We are now using this rod in all of our Stage 4 and up SBC engines. We also use this rod in our big block 505/540/555 engines, making approx. 700+hp.
If you do a search on the Scat Pro-Comp rods, you will find a vast amount of info on many car forums. All of the info is 100% positive. These rods are run in engines that not only produce high horsepower levels, but also run at continuous RPM. Notice the general appearance in the pictures. These rods do look impressive. The style is reminiscent of a steel billet rod.
The fact that these rods are incredibly strong and well made, coupled with the fact they are light weight and offer better clearance than any H-Beam rod on the market, made it an easy decision to use them in all of our high horsepower street/strip engines.
We use genuine Scat rods with ARP cap screws in all of our engines. Our Scat rods are bronze bushed, and unlike Eagle I beam rods, these are fully forged 4340 alloy.
We have noticed some engine builders using low cost generic rods and crankshafts in their engines. These non-branded, (no-name) products are often poor quality in many ways. You will notice many of the low end engine builders fail to mention the actual brand of the rods or cranks used in their engines. Upon further investigation you will find such parts not to be a branded name product. They may label these parts with a name, but one that is totally unrecognizable in the industry. Our experience in years past with such rods and cranks has been disappointing to say the least. Besides the obvious issues such as incorrect sizing and machining that is difficult to correct, the questionable alloy these items may be produced from and the potentially incorrect heat treating methods used, could prove to be disastrous. Little can be done to verify this and nothing can be done to correct it. Failures of such critical parts will usually result in catastrophic damage to the engine. As you may have noticed, this is why we specify the brand name and series of every part used in our engines.
Genuine ARP 8740 cap screws.
PRO RACE BRAND HARMONIC DAMPER, 6.75 DIAMETER INCLUDED.
Pro-Race brand damper is used on all of our engines.
INTERNALLY BALANCED, 6.75" DIAMETER REDUCED ROTATIONAL MASS, OFFERS EXCELLENT CLEARANCE.
1.52" THICKNESS, 2.38" THICKNESS WITH HUB
HEAVY DUTY SFI RATED FLEXPLATE MADE IN THE USA INCLUDED.
This SFI flexplate is made in the USA and will resist cracking and warpage to a very high degree. One good telltale in identifying a low quality flexplate is the lack of welding on each side where the plate mates to the ring gear. They usually have a pale grey color to them, as they are not coated, and will rust quickly. Ours are welded on both sides, and are much thicker than an OE plate, and are zinc dichromate coated.
We do offer this engine with a manual flywheel. In most cases we do have both sizes, 153 and 168 tooth, available.
Pictured below is our ABS crank polishing machine in action. We polish the crank on every engine we build. This extends bearing life, keeps oil cooler, and with the reduced friction, a slight increase in horsepower is gained. Many machine shops fail to do this. The finish on most cranks is at the bare minimum of acceptance, and we know this can affect bearing life. We have measured the RA finish with our profilometer, and found it to be as high as 25 RA finish on many of the cranks. We bring that number down to below 10.
Our CWT 5500 Balancer.
We do our own balancing with our new state of the art CWT 5500 Series balancers. The CWT 5500 is the ultimate for precision balancing. We now have three of these in our machine shop. We consider this machine to be highly advanced compared to the Hines balancer we once used. We balance every rotating assembly we sell within 2 grams or less at no extra charge. A balance sheet is included with your engine.
Three new CWT balance machines under one roof is a rare sight.
Our crew wrapping up for the day. Pardon the mess.
NKB 200cc ALUMINUM HEADS
Our new NKB-200 heads have been designed especially for us. After receiving many recommendations from our engine builders, we came up with the best quality, best flowing heads on the market relative to cost. The only way youâ€™re going to get a set of heads that flow as well or better will be to spend at least double the cost or more. We have installed these heads on all of our 383 and 406 engines for the past two years. Many of these engines were dynoed on our new Superflo dyno. The engines had every possible combination of cam, intake and carb. The results have been amazing. These heads are excellent in design and quality. Our choice of hardware and precision assembly also contribute to the performance and reliability of the heads.
In the flowchart below, the NKB-200s are superior to the Procomp heads in flow rates, and also edge out the Dart SHP heads on the intake side. The intake numbers are far more important than the exhaust. The overall average flow numbers on the NKB-200 heads are higher than most any brand of non cnc'd cast aluminum heads on the market.
The difference in horsepower and torque generated by the NKB heads is monumental compared to most all of the low cost sbc heads on the market. We offer several different cam choices with our 377 engine.
Here is a rundown on the hardware used in the NKB heads and the assembly process.
The retail cost at most High Performance stores on the PBM Competition valves is $239
We are now using the Competition Series PBM valves in all of our 377, 383 and 406 engines. These are considered a high end valve. These valves have an undercut and backcut feature.
The backcut feature reduces valve weight by an average of 12.5 grams per valve. This weight reduction of approx. 208 grams off the complete set of valves has a monumental effect on acceleration, deceleration, and valve train life. It may be difficult to understand how this works, but rest assured, this is a huge reduction. The valve spring compression and rebound action will remain stable for a much longer time running lighter weight valves, as well as reducing valve float.
The backcut feature is not be mistaken for undercut. These valves have both features. Backcutting is an additional radius, but located on the head of the valve to increase the flow numbers and reduce valve weight. The flow increase is approx. 3-6 points on the flow bench, and possibly more, depending on the initial flow rate of the heads.
According to one of our machinists who built Winston Cup engines for 15 years, the exhaust valves had an additional radius cut on the outermost edge that allowed a better escape of the exhaust gas. This cut on the exhaust valve is in addition to the back-cut feature. The competition series are made from a much higher temp alloy than most other stainless valves. There are at least three levels of stainless valves on the market, excluding those used in very high level racing such as pro-mod. The PBM competition series is compared to the highest level of those three. As a final note, backcutting a set of valves is said to improve flow in the low lift area, and this is most desirable on street rods.
Comp High Performance Dual Springs, Part Number 987-16
Our Comp springs are 1.43 diameter, with an inner spring and internal damper. Others are using springs that are much smaller in diameter. Smaller diameter springs may be in the correct spring pressure zone, but they usually have a shorter life. Comp springs are made in the USA. All of our engines using the NKB heads use these springs. Spring failures are near non-existent.
COMP CAMS "POSITIVE STOP" VITON VALVE STEM SEALS. # 529-16
Comp 10 degree machined valve locks.
We use only Comp Super 10 degree machined locks. Our head builder noticed the low grade locks on the market fit more loosely than he felt they should, not to mention the possibility that they were made of inferior metal. He envisioned the engine being much more prone to dropping a valve at high rpm. Using these locks, we have yet to have an engine drop a valve due to a valve lock failure.
Comp Cams retainers # 75740-16 and Comp Cams ID locators Part number: 4771-16
Our Comp Cams retainers # 75740-16 and Comp ID locators # VTH-4771-16 are made from 4130 chromoly steel. These retainers have a perfect fit with the Comp valve locks. We have used these on all of our engines for many years, and have had zero failures.
We hone all of the bronze valve guides with a ball berry flex hone to establish not only perfect clearance, but also a semi cross hatch finish for oil retention. We finish off with a natural bristle brush. The heads are then placed in our parts washer and cleaned with high pressure hot water, then pressure dried. Before installing the valves, we apply a heavy coat of engine assembly lube to the valve stems. The coating on the valve stems is essential to protect the bronze guides from gaulding on initial startup.
Our next step is to set the spring pressure to a predetermined pressure using a spring height checking device, most suitable for street rod use. The springs we are using allow for a near perfect seat to nose ratio. Be warned that some sellers of aftermarket heads may not be checking the installed height when assembling the heads, and may not be setting them up to the correct pressures. We have a full scale machine shop with several very knowledgeable engine builders that know and fully understand how to properly assemble a set of heads. Combine the possibility of poor assembly methods with incorrect or low grade hardware, and it is easy to see how failures can result.
Head gaskets are Fel Pro 1003 premium race grade series, and ARP head bolts, and rocker studs.
Scorpion Race series 1.5 OR 1.6 ratio roller rockers with 7/16 ARP rocker studs. We recommend the 1.5 ratio for better low end response and extended valve train life.
THE BEST HIGH PERFORMANCE RACING ROCKER ARMS MANUFACTURED IN THE USA.
We were amazed at the low level of sound produced in the valve train when we did a test run using our first set of Scorpions. We attribute this quiet operation to the close tolerances in the trunnion section. The trunnion barrels are also micro polished.
The rockers have a lifetime warranty. The aluminum body is made from a 7000 series aircraft alloy. Most rockers have a considerable amount of side play in the trunnion section, and may have an excessive amount of needle bearing clearance. The Scorpion does not have much of a loose feel in the trunnion. Many round track and drag racers run these at very high rpm levels and even run them on solid roller setups. With the milder spring pressures of our engines, these rockers should last a lifetime.
All Scorpion Rockers Feature:
Needle Bearing Fulcrum and Roller Tip, Centerless Ground Trunnion, Centerless Ground Pin & Roller, Burr-Free Thru Hole in Trunnion, Large Machined Seat, Thick Walled Adjusting Nut, Pedestals Machined from Solid Steel, Black Oxide Coated Steel Parts, & 100% CNC Machined.
HOWARDS TIE BAR LIFTERS, HOWARDS CHROMOLY 1pc. .080 WALL PUSHRODS.
We use Howards brand premium pushrods in all of our engines. They are lightweight in design, yet very strong. Made in the USA from 4130 chromoly steel. Regular hardened pushrods will most likely flex in the engine when running above normal RPM ranges, and risk bending under high RPM. These do not have the welded ball on the end. We only use the swedged one pc. design, which is a well proven design far superior to the style many others use in engines. 4130 chromoly steel is also much stronger, and will resist flexing. When a pushrod flexes in the engine, you lose lift. Don't be misled by the term "hardened," as this is nothing more than a stock style low cost push rod. They will flex in the engine or possibly bend permanently.
Our choice of lifters are the Howards brand tie bar lifters. These lifters are much costlier than the regular drop in hyd. roller lifters, and have many unique features.
We are offering four cam choices listed below in this engine. Read the specs carefully.
Cam choice # 1
Howards part no. 180345-10
Valve lift with 1.5 Rockers: Intake .565/Exhaust .580
Duration @.050": Intake .245/Exhaust .253
Lobe sep. angle: 110Âº
This cam is the most aggressive of the four choices listed. It will make its peak horse power at approx 6500 rpm. The idle is very radical. Power comes in around 3200 rpm.
We recommend a stall converter of around 2800-3200. Final gearing would need to be at 373 or numerically higher. A 373 final gear is most optimal with this cam, providing the car is reasonably light. This cam does make the most horse power but will trade off bottom end throttle response and low speed cruising in the low rpm range unless your car is setup in pro-street form. The idle sound with this cam is very erratic.
You would not be able to run an overdrive trans, power brakes, or air conditioning with this cam choice. Valve train life and reliability is reduced with this cam as compared to the other choices. This would only be a concern for those wanting to drive their vehicles on long trips or with frequent use. This cam choice puts your setup nearly into the Pro-Street league.
Drivability is fair at best with this cam, unless you have a very light car, with a decent final gear.
If your car is over 3400 lbs, we strongly advise against this cam, unless you have a final gear in the 4.10 range or numerically higher. If you're on the fence with this cam choice and the one below, then you may want to go with this cam and keep the rocker ratio at 1.5, or go with cam choice 2 and go with a 1.6 ratio. That would put you somewhere in the middle of cam choice 1 and 2, at least in respect to valve lift.
If you choose cam choice 1 with the single plane intake combination, it is highly recommended that you upgrade the ignition system to an MSD Pro Billet distributor, and CDI unit. You should also upgrade the carburetor to the SS Series for optimal performance. These important upgrades are essential for improved idling and overall performance. If you do decide to use the MSD Pro Billet distributor we suggest you use the black timing degree bushing to increase the initial timing and possibly the lighter springs to control how soon the total mechanical advance comes in. You may even "lock-out" the distributor, depending on you cars overall setup. The CDI unit will make a huge improvement in how the engine runs at idle. Low speed cruising will be greatly improved, as well as high rpm operation. The SS carb upgrade is an all out double pumper carb, and gives the engine instant throttle response. If you choose cam choice 2 you may not require these upgrades but should consider them to enhance the performance and drivability of your engine.
There is one more upgrade that I feel would enhance overall performance and add stability and longevity the valve train. The Max Effort Tie bar lifter upgrade is essential for those that choose to run hard. We use the regular Howards tie bar lifters with this cam and they do well, but the Max Efforts have proven to be much more stable in the upper rpm ranges. Any over-revving of the engine beyond it's peak power may bring on valve float when using the regular tie bar lifters. The Howards Max Effort Tie Bar lifters will not only improve performance but also allow the engine to operate very well in its peak rpm range and beyond. This is a very nice upgrade for any street rod running into the upper rpm ranges.
Cam choice #2
PART # 180265-10
Valve lift with 1.5 Rockers: Intake .530/Exhaust .545
Duration @.050": Intake .233/Exhaust .245
Lobe sep. angle: 110Âº
Cam choice 2 is considered still somewhat aggressive and improves drivability compared to cam choice 1. This cam will still have an aggressive lopy idle. You would require a stall converter in the 2500-2800 range.
Final gearing should still be at approx. 3.73. If your car is in the 3800 lb weight range or more, we recommend cam choice 3 or 4. Hp numbers will drop with this cam, around 20-25 at the most. Combine this cam choice with the dual plane intake option and hp numbers will fall approx another 10-15, but bottom end torque is greatly improved, as well as drivability.
It is not recommended to opt for the single plane intake if your car is in the medium to heavy weight range. They do not operate as well in the lower rpm range. The low end torque with this cam comes in sooner than cam choice 1, but you must still set the car up with proper gearing and converter stall. This cam is our most popular and delivers great bottom end power and very good drivability.
You may not be able to run an overdrive trans with this setup, power brakes are a possibility. We do not recommend this cam if your going to run an A/C unit. Our cam choice 3 or 4 would be much more suitable.
Cam choice #3
PART # 180245-10
Valve lift with 1.5 Rockers: Intake .500/Exhaust .510
Duration @.050": Intake .225/Exhaust .231
Lobe sep. angle: 110Âº
This cam choice (3) is the perfect all around setup for those wanting excellent bottom and mid range power, while still generating decent power at the top. Horsepower rating would drop an additional 10-15 hp below the cam choice 2. Drivability and street manners would be considered excellent. Heavy cars, upwards of 3800 lbs or more, would do well with this cam choice. No need for a high rpm stall with this cam, but you would still require a stall in the 2200-2500 rpm range for optimal acceleration.
If your car is in the heavy weight range, and/or geared on the steep side and you want much better streetability, then this is the correct cam choice. You still want to keep the final gear ratio at approx. 3.20 or numerically higher. If you have an overdrive trans., then this cam, coupled with the dual plane intake, would allow the engine to cruise in overdrive with rpm in the 1950-2050 rpm range. Should you have a Turbo 350 trans, then this cam choice would allow you to run a somewhat taller final gear to allow decent highway driving in the lower rpm ranges.
You may choose 1.5 or 1.6 rockers with this cam, but we recommend the 1.5 rockers for even better low end response, especially if you plan on running an overdrive transmission. You can also expect a much longer valve train life with this cam compared to the larger cams listed above, especially with the 1.5 ratio rocker choice.
Carb size when using this cam will drop. You'll notice slightly better mileage and better throttle response with this carb versus the larger carbs required when running the larger cams. If your vehicle is very heavy, over 4400 lbs, then we recommend our cam choice #4.
Cam choice #4
PART # 180315-10
Valve lift with 1.5 Rockers: Intake .465/Exhaust .470
Duration @.050": Intake .209/Exhaust .215
Lobe sep. angle: 110Âº
This cam choice (4) has a lower lift and duration than the other two offered above, and is highly recommended for use in heavy cars or full size sport trucks. The low end response with this cam is very good. Horsepower rating would be approx. 430 at 5,500 RPM with 1.6 rockers and a single plane intake.
The rule of thumb for cam size: the smaller the cam in a given application, the better will be the low end response. One more benefit to the smaller cam is the reduced requirements for lower gearing and higher RPM stall converters. A final gear ratio of 3.30 would be acceptable with this cam. The bottom end power would be much better with this cam than the two other choices above.
This would be the best choice for running an overdrive transmission such as the 700R4 cruising at around 1950 RPM in overdrive. A stock or near stock stall converter may be used with this cam, but for improved acceleration a 2000-2250 stall is recommended especially in heavy vehicles with a tall final gear.
Valve train life is greatly extended with this cam as compared to the others, and drivability is at its best. Low and mid throttle response is very strong. This cam choice will also produce the greatest amount of vacuum at idle compared to those listed above. You may run power brakes with this cam, and it may allow the use of the vacuum advance for improved low end power and fuel mileage.
If you need help in selecting a cam to suit your needs, feel free to contact our tech. department.
THE FOUR CAMS LISTED WILL COVER MOST NEEDS FOR ANY STREET ROD OR SPORT TRUCK.
QUICK FUEL SLAYER 600-750 CFM CARB, DEPENDING ON CAM CHOICE.
Quick Fuel Technology (QFT) has engineered its new Slayer series vacuum secondary street carbs with all the features. The Slayer is not some stripped-down off-shore QFT copy, it features the same QFT race engineering, all-aluminum construction and hand-built quality that goes into all QFT race-winning carburetors.
The Slayer's incredible value is made possible by QFT's new CNC machining centers and the unique design that utilizes a secondary metering plate with changeable jets, eliminating the costly secondary metering block unneeded for most street/strip cars. The majority of fine tuning on a street carburetor is done on the primary side, and the Slayerâ„¢ provides all of the popular options: changeable idle air and high-speed air bleeds, 3-stage emulsion circuits, changeable primary idle feed restrictions and power valve restrictions.
A truly welcomed feature is the QFT QuickSet adjustment on the vacuum secondary diaphragm that provides a quick external twist adjustment without changing springs. Secondary metering can be altered with changeable main jets and the secondary float is also notched for jet extensions.
Additional features are a fully adjustable electric choke, and a semi polished finish that will improve any engine compartment. The Slayerâ„¢ 750cfm (Part # SL-750-VS) features a 1-11/16" throttle bore and a 1.375" venturi.
You have a choice of single or dual plane intake. The single plane intake (1st pic below) should only be used on cars that are very lightweight and have good hood clearance.
Dual Plane Intake shown below. This is a large runner dual plane intake. They make excellent mid range power.
Polished intakes also available.
Pictured below is the Edelbrock Performer EPS dual plane intake. If you're going with cam choice # 2 or 3 and require more bottom end power, we strongly recommend this intake. This intake offers incredible low end response and has excellent hood clearance for those installing this engine in a C3 Corvette with a non-cowl stock hood.
304 STAINLESS ALLEN HEAD INTAKE BOLTS ARE USED ON ALL OUR ENGINES.
The timing components are the Cloyes Race Billet double roller timing set. Part # 9-3645X3
We use the top of the line Cloyes timing set. The difference in quality is dramatic compared to the common true double roller setup. The chain is made in Germany, and the sprockets are hardened billet steel (upper and lower) and made in the USA. These sets are hand matched for selective sizing.
The cost on this high end timing set is approx $139, about four times the cost of the low level budget timing set used by many other engine builders. Should you ever want to confirm that this is what is actually in your engine, you can remove the timing cover, and you will notice the upper gear has a full array of lightening holes.
This top of the line timing set is offered in three different chain tension setups, allowing us to set it up perfectly every time. One more benefit is that timing accuracy is very precise and will remain that way. This timing set will likely last for the life of the engine. This is what you will find in most solid roller engines, as they have very high spring rates, and create an enormous load on the chain and gears, compared to non solid roller setups. It may seem like a bit of overkill to use such a high end timing set, but the versatility and extreme quality outweigh the cost, in our opinion.
Pictured below are our most popular valve covers. They are fabricated aluminum, and very high quality. You may select from any of the valve covers we have listed at no additional cost for your engine.
OUR RETRO STYLE TALL FINNED VALVE COVERS HAVE BECOME VERY POPULAR. YOUR CHOICE.
POLISHED ALUMINUM TIMING COVER.
We use only Felpro seals and gaskets with our timing cover.
STAINLESS FLEXIBLE ENGINE OIL DIPSTICK. BILLET ALUMINUM HANDLE.
Included with all our sbc engines.
Melling M-Select Oil Pump, and M-Select Drive rod with ARP stud.
The M-Select series oil pump by Melling has several important upgrades compared to the regular Melling M-55 Series. The gears are billet steel, and the body is stronger, coated with corrosion-resistant nitrite. This oil pump also includes the M-Select drive rod. Both components are far superior to the regular Melling oil pump and drive rods used by most other engine builders.
Champ premium oil pan.
Pictured above is the oil pan included with this engine. The Champ oil pan used on this engine has an 8 qt. capacity. It has an elaborate oil control system. Features windage tray, crank scraper, .055 gauge outer shell, with reinforcing ribs. Champ oil pans are made in the USA. All QRP Series engines will come with the Champ oil pan. If your car will not allow the use of the large capacity Champ oil pan, we have the same series pan in stock appearing form. 5qt. capacity and still has the windage tray, and crank scraper.
We do not use the knock off oil pan gaskets on the market. Felpro premium oil pan gaskets are used on all of our engines.
We use this premium studded mini nut set for oil pan and valve cover fasteners. The nuts have a serrated face and built in washers. This is the ultimate set for securing the oil pan to the engine and is far superior to the typical bolts used by most other builders. We use this set on all our engines.
Listed below are more of the items installed on the outside of the engine, which makes it a "Turn Key" engine.
Billet Aluminum Breather set.
If you chose cam choice 1 or 2, then we highly recommend using an exhaust evac. system. The vacuum created by the engine is somewhat insufficient when using these larger cams, heads, carb and intake to operate a pcv system at its best. The exhaust evac system will pull the crankcase gases out of the engine at a very smooth and controlled rate. This allows the rings to seat in much faster and better, and can increase horse power to some degree by reducing crankcase pressure. Another benefit of the evac system is that you're not contaminating the fuel and air mixture with semi-burned byproducts from the engine oil and combustion process.
After the engine is completely broken in, the pcv setup may be sufficient. However, it may not be the best choice. The break-in time may also be slower with the pcv setup.
We also offer a vacuum pump system for the ultimate in crankcase pressure control.
If you do decide to use an exhaust evac system, we have a few more recommendations. The bullet style perforated mufflers, like those made by Magnaflow and many other companies, must be used. In our opinion, they sound the best and, most importantly, they allow the exhaust evac system to work properly. Magnaflow is a popular brand of the true straight through mufflers, and there are several other brands on the market such as Corsa, Borla, and Bullet. The sound level is controlled by the length you choose. The 12-16 inch length sounds the best to us. These mufflers have smooth perforated inner walls. They should not be confused with traditional glass packs with fluted walls, which are very restrictive and have a somewhat sloppy sound.
Traditional chambered mufflers, like Flowmaster, create a back pressure pulse that will interfere with the operation of an exhaust evac. system. Chambered mufflers have the reputation of helping bottom end throttle response, but you will have a decent amount of bottom end power with this engine, especially if you have chosen cam choice 2, 3 or 4. In our experience, the straight through perforated mufflers sound and perform better in every respect, and allow the proper use of an exhaust evac. system. More info. on this subject below.
BILLET ALUMINUM TIMING POINTER. VERY FEW SELLERS FINISH OFF THEIR TURN KEY ENGINES AS WE DO.
We did not offer this billet timing pointer in the past. However, we noticed that there was a birds eye view of the timing pointer from the driver side of the engine, so we decided to use these on all of our engines.
As you can see in the picture below, these timing pointers have a glove like fit.
High volume polished aluminum water pump with an aluminum impeller. This is a very high quality unit.
120 AMP ONE WIRE CHROME ALTERNATOR AND ALUMINUM BRACKET KIT.
WATER PUMP, CRANK, AND POWER STEERING PULLEY WITH BRACKETS, INCLUDED.
If your vehicle is a pre 75 model that came with a point style distributor, then you should opt for the full size HEI dist with the OE style cap, not the Super Cap. Both distributors are identical, but the OE style coil cover does allow a slight more firewall tunnel clearance. Some models may not even allow the use the OE style HEI distributor. If you think you are going to encounter this problem, then you may choose our small base Ready To Run HEI distributor. It has a small base and is identical in size to the original point style distributor. It will require the use of an externally mounted coil.
The plug wires are included but not installed on the engine. Due to the many different style headers being used, we will send the universal wires with the engine for custom fitment.
TAYLOR SPIRO PRO SERIES 8mm UNIVERSAL IGNITION WIRES, 90 DEGREE BOOTS AND OUR 65K VOLT HEI DISTRIBUTOR ARE INCLUDED.
The distributor will be installed in the engine.

IMPORTANT NOTE ABOUT DE-TUNING.
For those with very heavy vehicles, such as 4x4 quad cab trucks, 3/4 ton trucks, and crew cab/ex-cab trucks, Suburbans, plus trucks that may do light to medium trailer towing, we strongly recommend the de-tuned version of this engine.
For those wanting to run a supercharger, we recommend our extra deep dish pistons with the 75cc heads regardless of the vehicle.
Our machinists each have many years of experience in building racing engines. This very critical work is done to exacting specs and with great care. Many vendors do not have machinists with the experience or the proper equipment that we are fortunate to have. We have built engines that cost upwards of $50,000. All of our engine builders have been in the engine machining and engine building line of work for their entire working lives. Their ages range from 38 to 65. We have a total of seven machinists/engine builders.
