BBC CHEVY 582 DART SHORT BLOCK FORGED PISTONS K1 CRANK, SCAT RODS +12CC DOME TOP

Important note.(10/14/2022)

Fall is here, and as usual this is the slowest time of the year for us. The timeline to build a short block kit now has been greatly reduced to around 5-10 days in most cases. We have actually built up stock on our most common short block kits and could possibly have one available for delivery in approx. 2-4 days. Race build season will start around mid January and this timeline to get a short block kit will change greatly. 

  Total Seal High Performance Rings.

We recommend that you check the thrust clearance on the crank before assembling the engine. This is recommended on any crankshaft, regardless of brand or cost. Also be sure to check your main and rod journal size.

Our choice of rods are the Genuine Scat brand heavy duty 6.385 H-beam rods with ARP cap screws.

The Scat rods do have genuine ARP 8740 Series 12 point cap screws. These rods offer excellent block clearance in the lower end of the cylinders.

Genuine ARP 8740 cap screws.

The Scat rods do have genuine ARP 8740 Series 12 point cap screws. Some cams may require slight clearancing of the rods. Be sure to do a roll over test after installing each rod. 

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.

Many of the inferior "no-name" rods on the market will also have "no-name" rod bolts in them. We have seen these bolts before, and they are very low quality. They don't have ARP's rolled thread design, and they don't torque down with the same characteristics as a genuine ARP bolt. It's not just a matter of having a different brand bolt in the rods; these bolts are low quality in many ways. They have been known to fail in engines to a much greater degree than a high quality rod bolt, and this failure usually causes catastrophic damage in the engine. Beware of rods that don't mention the rod bolt brand. As far as we're concerned, ARP bolts are the only brand we would ever use or accept in a set of rods.

Before the engine is assembled, we strongly suggest checking the rods on a Sunnen machine for sizing on both ends. We recommend this with any rod regardless of cost or brand. It is not uncommon to find some of the rods requiring a slight bump through the hone for perfection in sizing and roundness. We also offer this kit with a proofed set of rods. This is an excellent choice for those wanting to build the engine on their own. 

  KING MAIN AND ROD BEARINGS INCLUDED.

We have noticed others using a low grade knockoff brand damper/balancer, and we have encountered them in the past. They are substandard in appearance, and are often out of spec. The timing marks were also poorly marked on some of the balancers we have come across. You don't want a balancer coming off or one that is improperly weighted. Another problem with low grade dampers is the elastomer bonding can lose its adherence to the inner and outer structure. This problem is referred to as a slipped damper. We have only encountered this once in 10 years with the Pro-Race brand dampers. 

We know of several competitors including these balancers with rotating assemblies. The ProStreet brand is far superior to most any we have ever seen. They were once known as a knockoff product, and have become one the best values on the market, without comprising quality whatsoever.

HEAVY DUTY FLEXPLATE INCLUDED. 

HEAVY DUTY FLEXPLATE. This flexplate will resist cracking. 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 either zinc dichromate or black powder coated. We would never use the thinner OE style plate on an assembly like this. 

We do offer this assembly with a manual flywheel. See our other listings. In most cases we do have both sizes, 153 and 168 tooth, available.

WARNING: the flexplate and crank have a dowel pin hole. You must align the flexplate and crank dowel pin holes, but do not use a dowel pin. The flexplate was aligned to the crank when we balanced the assembly, and must be installed the same way. 

 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 assembly. 

Three CWT balance machines under one roof is a rare sight. 

Our crew wrapping up for the day. Pardon the mess.

Our thoughts on what the competition has to offer.

Many short block kits we see on the market are not using the most suitable parts. We hope you can value the fact that we have put together an above average short block kit. The failure rate with the parts we use is near non-existent. It was through trial and error in years past that taught us where to draw the line with low cost parts. We are out-priced by many others selling short block kits that include parts with high failure rates. Many of these parts also pose a great problem due to the fact they require additional machining and can end up costing you a great deal more money and time. If you're going to have a machine shop build your engine, we strongly advise you get an opinion from them on the parts you're going to be bringing to them. Rest assured they will find no problem with the quality of our parts. We have also seen sellers offering parts that are not compatible with what most people are building. We have seen several sellers offering no-name brand rods with an assembly. These type of rods also have no-name bolts in them. It is our strong advice to avoid this grade of rods. The low grade dampers and flexplates are also another problem. Another area of concern would be balancing. Not sure how much attention these sellers are giving in this area. We spend up to two hours balancing an assembly, and using the very best up to date balancing equipment on the market. If the assembly is not balanced properly, it will hammer the bearings out of the engine, not to mention there is nothing worse than an engine that lacks a smooth feel and sound when under load.

We offer this short block kit with selected upgrades. Listed below are some of the most requested ones. Many not only improve performance, but further enhance the reliability and longevity of your engine, along with resale value. Please go to the "UPGRADES" category of our eBay store to add upgrades.

Some of the benefits of the new Manley Pro-Series crankshaft. This upgrade is offered at a price of $285.00

Manley Pro Series crankshafts can make your engine bulletproof. They feature forged 4340 construction and undergo a multi-step heat-treatment process and are then nitrided for added strength. The crankshafts are stress-relieved, shot-peened, and magnafluxed. Manley Pro Series crankshafts have micro-polished large .125 in. radius journals, gun-drilled mains, and lightened rod journals for weight reduction. The counterweights are fully profiled and they are designed for internal balancing. These crankshafts will include a spec. sheet that validates journal sizes and checks for taper on each journal as well as finish quality.

SFI Certified Flexplate: This is a very low cost upgrade and may be required when racing your car at certain tracks. The flexplate that comes with this assembly is a heavy duty plate, but the SFI certified plate is one step up in quality and safety. This SFI plate is made in North America. We noticed these have much less run-out and warpage than we see with many other plates on the market. Plates with too much run-out and warpage can cause a host of problems for your transmission and starter, and affect balancing. The low cost to upgrade to this is well worth, it in our opinion.

Cost of this upgrade is $16.50 We have this upgrade featured in our other listings. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store. Before you finalize your purchase of this kit, you may add any of these upgrades to your shopping cart.  Please go to the "UPGRADES" category of our eBay store to add upgrades.

SFI Rated Billet Steel flywheel upgrade/option for manual transmission. Upgrade to a SFI billet steel flywheel 168-tooth or 153-tooth for manual transmissions. We highly recommend the SFI billet steel flywheel for those running hard. These are fully cnc'd and far superior in many ways compared to the regular cast iron flywheel.

Cost for the SFI billet flywheel option can vary depending on availability. We carry two lines of the SFI plates, PRW and Ram. The Ram plates are a much higher grade product. We have this upgrade/option featured in our other listings. There will be a Chevy 153 tooth and a Chevy 168 tooth size available. Be sure you know the size you need. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store. Before you finalize your purchase of this assembly you may add any of these upgrades to your shopping cart.

SFI damper: Offers an extreme level of safety against breakage, and is very resistant against slippage of the elastomer damping material. SFI dampers are not only made from a better grade of steel, they are also constructed differently and have a much better appearance. They usually last much longer than a non-SFI damper. Many drag strips require this on engines producing high horse power levels. The SFI certification is laser etched into the side. Damper failure rates are much higher on engines using a non-sfi damper coupled with hp ratings exceeding 500 and turning 5600 rpm or higher.

Cost of the SFI damper upgrade is $69.50 We have this upgrade featured in our other listings. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store. Before you finalize your purchase of this kit, you may add any of these upgrades to your shopping cart.  Please go to the "UPGRADES" category of our eBay store to add upgrades.  

Crank polishing: Extends bearing life, reduces oil temp, frees up a slight amount of average horsepower. This is a very low cost upgrade, and in the world of mass production, most cranks do not come with a true polished finish. This is why most machine shops have a machine to do this. The difference is dramatic between a crank right out of the box and one that we have polished. Bearing companies claim that cranks that have better finishes on the journals will survive the break-in better, and have much longer bearing life. We do a two-step process and bring the RA numbers down in the single digit range. We have the most advanced crank polishing machine on the market. 

Cost for the crank polishing upgrade is $38.50 We have this upgrade featured in our other listings. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store.

Wiseco BoostLine Rods and Tool Steel Wrist Pin upgrade. For those wanting ultimate protection in their engine, this upgrade is the answer. The Pro-Pac kit comes with the Wiseco BoostLine rods, tool steel thick wall wrist pins, and ARP 2000 rod bolts. This is an excellent upgrade for those running any type of forced induction, (blowers, NOS, twin turbo, high compression builds). This is also an excellent upgrade for those running naturally aspirated street rod engines. Connecting rod or rod bolts and/or wrist pin failures will usually cause catastrophic damage to the engine. The Pro-Pac kit can handle horse power levels in the 2,000+ range. The 4340 alloy has been through a very special heat treating process. These rods are what we use on all of our extreme high HP applications. As mentioned, this is also an excellent upgrade for medium HP builds that may encounter some hard run time. BBC engines that have been stroked above 4.250 can greatly benefit from this setup. It's well known that engines with long stroke cranks have a greatly increased load on the rods and wrist pins when encountering rpm in the upper ranges. We consider this upgrade very valuable for those that encounter any serious running. The Pro-Pac upgrade includes three actual upgrades: the rods, tool steel wrist pins, and the ARP 2000 rod bolts. Our company founder, Skip White, sums this upgrade up in a few words: "bullet proof." The idea that when you bring your engine rpm up to its limits, and know that the breaking point is often not far away, this upgrade offers a great amount of protection from what could be total engine destruction.

Cost of this upgrade is $965.00 We have this upgrade featured in our other listings. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store.

BoostLine connecting rods are designed from the ground up for high-power forced induction and nitrous applications as well as naturally aspirated engines. A patented 3-pocket design, forged from a special 4340 alloy, maximizes strength while minimizing rotating weight. This revolutionary design dramatically improves the rod's big-end stability under tensile loads and provides a 60% improvement in bending strength and 20% stress reduction in tension compared to H-beam designs. All of these benefits make BoostLine rods ideal for any street rod or racing engine.

 

In addition to BoostLine's innovative design, comprehensive real-world testing, finite element analysis, and meticulous quality control ensure that all BoostLine rods are fit for 2,000-plus horsepower (8-cylinder applications).

 

All BoostLine rods include high-quality ARP 2000 bolts. Every rod is inspected and finish-honed in America in addition to being analyzed on a Zeiss CMM as part of the final inspection. A detailed inspection report measuring to .0001 in. is provided with every set of BoostLine rods. 

 

Also included with this upgrade are the JE tool steel wrist pins.

 

 

For high-impact, drag race, and endurance applications, JE Pistons offers the Series 52 wrist pins. These pins are constructed from 52100 high carbon bearing steel and through-hardened for added stability. All JE pistons are super-finished on both the outside and inside diameters to help reduce piston pin bore wear and minimize fatigue cracking, adding to the overall strength and reliability of the wrist pins. Employing the latest in technology and quality control, the Series 52 wrist pins are checked for the tiniest flaws and to ensure the roundness of each pin. JE Pistons Series 52 wrist pins are available in a variety of lengths, diameters, and wall thicknesses. They are specifically developed for use with JE pistons.

Clevite Bearings: We find the Clevite bearings to be a somewhat better product overall. Clevite is what we now use in all of our engines. This is not to say that King bearings are faulty in any way, but under certain conditions, we have seen fewer problems develop with Clevite bearings during break-in. We have sold King bearings for many years and do not hear of problems from our customers, but our experience on the dyno has shown the Clevite bearings have a better surface appearance upon tear-down after many dyno passes.

Upgrade to Clevite "H/HN" Series (with forged crank) bearings is $55.00

We have these Clevite bearing upgrades featured in our other listings. You can see these and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store.

Rod sizing:  Sizing the big end and wrist pin bushing on the Sunnen machine saves a trip to the machine shop. All rods, regardless of brand, should be checked for sizing on a Sunnen machine, and corrected if needed. You will seldom see a complete set of rods that have  perfect sizing on both ends right out of the box.

Cost of this rod sizing upgrade is $89.50 We have this upgrade featured in our other listings. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store.

Race balancing: This is for those who want the engine to operate virtually vibration free at high rpm. Extends engine life and frees up a few more horse power. This is a somewhat labor intensive procedure and is not required, but the feel of an absolutely vibration free engine at high rpm is desirable by many. The standard balance job that is included with this assembly at no extra charge is certainly sufficient. With a race balance job, all pistons and rods are match weighed to within 2/10's of a gram or less, and the final balance is brought down to around 1 gram plus or minus. An ultra smooth engine at high rpm has a noticeable feel and sound to it. If you do not opt for this upgrade, the assembly will still be fully balanced. We spend a good hour and a half doing the regular balance work, and it will certainly meet your needs.

Cost of this race balancing upgrade is $125.00 We have this upgrade featured in our other listings. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store. Before you finalize your purchase of this kit, you may add any of these upgrades to your shopping cart.  Please go to the "UPGRADES" category of our eBay store to add upgrades.

Block prep package: This upgrade includes notching the block on our Centroid cnc machine to allow additional clearance for the crank if necessary. We also de-burr the block, hone the lifter bores to spec, chamfer the top of the cylinders, and lifter bores, and install the special cam bearings and freeze plugs. The block is then thoroughly cleaned in our block washing machine. We find this upgrade essential for those lacking the proper equipment or knowledge to perform this correctly.

Cost of this block prep package is $225.00 We have this upgrade featured in our other listings. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store.

BBC Short Block Kit Assembly upgrade: This upgrade includes everything in the Block Prep Package plus assembling the short block kit. If you choose this upgrade, DO NOT also include the block prep package in your cart.

Cost of this BBC Short Block Kit Assembly upgrade is $455.00 We have this upgrade featured in our other listings. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store.

Preparing the block in our Centroid cnc machine for precise notching, if necessary.

The blocks are washed in a dedicated block cleaning machine.

 

Pictured above is the final rinsing and drying to remove the cleaning solvents.

The upgrades above are all available in our other listings. Some of these are often requested by those building an engine without a machine shop. We find most of these upgrades very valuable for those wanting to take longevity and durability to the next level. They are all bottom end related, and that's an area worth investing a few more dollars into, in our opinion, especially if you're planning on running long and/or hard. These upgrades are also valuable for your build history on your engine, and would certainly increase the resale value of your engine, should you ever sell it. 

A final note.

Our eBay user id is: skipwhite, and our eBay store name is whiteperformance1. You may have noticed other sellers using a similar name offering similar products. These other sellers have capitalized on our name as we see it, and many customers searching for us will inadvertently find them, thinking we are one in the same company. There is only one "Skip White." We are the original premier eBay seller under this name since approximately 2003. We have no other eBay names, nor are we associated with any other company regardless of the similarity in the name or location. Our official company name is Skip White Performance. Please see the article below for a more detailed explanation.

The real story...Skip White Performance vs. White Performance & Machine

I'm sure many of you have noticed there are 2 high performance engine builders in Kingsport, TN with similar names, and this has led to a great amount of confusion.

We are Skip White Performance, NOT White Performance and Machine. 

Now you know the real story, and we hope this helps with the confusion.
