Compression Ratio Chart

The calculations below assume your pistons are at zero deck. Let's say your compression calculates out to be 10.86, for example based on having the pistons at zero deck (flush with the deck), but your pistons were going to be .005 in the hole, then the comp. ratio would only drop to 10.72, and if left .010 in the hole, then it would drop to approx. 10.59 We do recommend having your block decked to allow the piston to set anywhere from flush (zero) to .005 in the hole for optimal performance. We used a 4.200 head gasket diameter, and a .040 head gasket thickness in our calculations to come up with our comp. ratio values.

The Wiseco forged pistons are rated very high in the street/strip performance industry. Ours
are made using the 2618 aircraft alloy and have fully machined crowns. Most lower cost forged pistons on the market do not use this alloy, and they do not have fully machined crowns. We prefer the 2618 alloy over the lower cost 4032 alloy. This alloy may fragment from the effects of detonation and if this happens, it can be very destructive to the engine.
The 4032 forged alloy pistons are fine for stock or mild engine builds, but should never be used in carbureted engines built to high horse power levels.
The forged 2618 alloy piston is much more resistant to the effects of detonation and heat.

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 pistons have a compression height that is .010 taller on bbc pistons, and .015 taller on sbc pistons, as compared to most all of the catalog pistons on the market. We find this to be a very valuable feature.

Since our pistons sit at a taller than normal compression height, you will only have to remove approx. .005-.010 off the deck surface of a virgin block to achieve a zero deck (flush with the deck surface). This maintains the deck's thickness, making it much stronger than a block that has been cut down .025. The engine will also run a bit cooler with a thicker deck. It's well known that the deck dissipates much of the built up heat an engine generates. This also allows for future deck re-surfacing without compromising the integrity of the block. Most all catalog pistons on the market require cutting the deck surface around .025 to achieve a zero deck. A zero deck is very important as it keeps the quench/squish zone at or near an optimal .040 distance. Be sure and let your machine shop know what the compression height is on these pistons before they machine your deck surface.


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.

We have built approximately 5000 engines using the Wiseco forged 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. For the slight increase in cost, this is the best value on the market.

The Wiseco forged pistons are one of the highest rated on the Market. Very highly regarded in the street/strip community.

We do our own balancing with our brand new, 2013 model CWT 5500 Series Balancer. The CWT 5500 is the absolute ultimate for precision balancing. When we balance the assembly for this engine, it will be to very high specs, usually within 1-2 grams. We include a balance sheet with your setup.

READ THIS LISTING COMPLETELY BEFORE YOU BUY ELSEWHERE!

This assembly uses a Scat fully forged 4340 crankshaft and 4340 Scat rods, Mahle metric rings, King bearings, ProStreet damper, and a 157 or 164 tooth HD flexplate. See our other listings for various piston bores in flat or dish style. See details in this add for actual specs of this assembly.

The bearings are included with this assembly.

The picture below is a generic file photo of a Scat crankshaft. You will receive the correct model packaged in the original Scat box.

 photo SCATCRANKANDBEARINGS.jpg

The machinist who does our balancing made special note of how much harder these cranks were compared to any of the other cast nodular cranks on the market.

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 check your main and rod journal size, as it's also not uncommon to find some cranks on the small or large side by as little as half a thousandths or less.

On occasion, our engine shop requires a half shell to correct this for perfect clearance. I would say this happens on about one out of 20 engines, but we really try to keep our tolerances in the middle zone. If you encounter this, we have 1 thousandths under bearings, and you should use them if needed, as this is important for engine longevity.

Don't confuse what we are saying with a turned crank. Those cranks are smaller by 10 thousandths or more. It's not uncommon for many GM stock cranks to have 1 under or over bearings in them right out of the factory. We rarely run into this, but don't assume anything. Just check before installing, and let us know if you need a set of 1 under or over bearings or the half shells.

GENUINE SCAT H-BEAM BUSHED CONNECTING RODS WITH ARP 12 POINT CAP SCREWS ARE NOW USED IN ALL OF OUR ROTATING ASSEMBLIES AND 347 STROKER ENGINES.

The quality of the Scat rods is unsurpassed by any of the low cost no-name rods on the market and they exceed the quality of some of the branded names as well.

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 sellers using generic rods and crankshafts in their rotating assemblies. These non-branded (no-name) rods and cranks are often poor quality in many ways. You will notice many sellers fail to mention the actual brand of these products. 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. Failures of such critical parts in your engine may result in catastrophic damage. Machine shops are sometimes able to correct some of the problems with these low quality rods and cranks, but at great expense to the customer. As for the questionable alloy these items may be produced from and the potentially incorrect heat treating methods used, little can be done to verify this and nothing can be done to correct it. As you may have noticed, this is why we specify the name, brand, and series of every part used in our assemblies.

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.

KING HP HIGH PERFORMANCE MAIN AND ROD BEARINGS ARE INCLUDED.

MAHLE PLASMA MOLY RING SET INCLUDED. 1.5mm 1.5mm 3.0mm file fit.

PRO RACE BRAND HARMONIC DAMPER, 6.40 28oz DIAMETER INCLUDED. THESE ARE VERY HIGH QUALITY ITEMS. YOU SHOULD NEVER USE AN OLD DAMPER/BALANCER.

 photo ProStreet4dampershires.jpg

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, but they are usually out of spec. We don't have anything against knockoff products if they meet our standards and offer a good value. We think it is great that many of the name brand companies are getting their just rewards for what we consider nothing short of offering overpriced goods. Take our word on this, you don't want a balancer coming off or one that is improperly weighted. The timing marks were also poorly marked on some of the balancers we have come across.

We know of several competitors using these balancers. 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.

FLEXPLATE INCLUDED.

 photo tci-399373.jpg

This flexplate will resist cracking and warpage, leading to imbalance in the engine.

We do offer this assembly with a manual flywheel. See our other listings. We do have both sizes.

WE FOUND NO TWO FLEXPLATES TO BE REMOTELY CLOSE IN THIS RESPECT. THE MASSIVE WELDING ON THESE PLATES AROUND THE RING GEAR ON BOTH SIDES AND ATTACHING THE WEIGHT IS VERY INCONSISTENT AS FAR AS BALANCING IS CONCERNED, SO WE DO SEND THE ACTUAL PLATE USED WHEN BALANCING AND SERIAL NUMBER IT TO MATCH THE REST OF THE ASSEMBLY.

Many rotating assemblies we see are not using the most suitable parts. We hope you value the fact that we have put together an above average assembly. Please read the full listing.

We offer this assembly 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.

Note: The upgrade prices below are subject to change. Refer to the actual upgrade listing for the exact price of these upgrades. The changes are usually very small if any.

Flywheel upgrade/option for manual transmission. Upgrade to a 168-tooth or 153-tooth flywheel for manual transmissions.

Cost for this option is $105.00 We have this upgrade/option featured in our other listings. There will be a 153 tooth and a 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.

SFI Billet Steel flywheel upgrade/option for manual transmission. Upgrade to a PRW brand billet steel flywheel SFI rated 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 is $169.00 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.

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 450 and turn 5600 rpm or higher. We strongly recommend this upgrade for those running hard.

Cost of the SFI damper upgrade is $69.50 We have this upgrade featured in our other listings.

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.

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. This is due to the fact that Clevite H/HN series bearings use a slightly harder aluminum alloy.

Upgrade to Clevite "H/HN" Series bearings is $106.00 (Use only on 4340 forged crank upgrade.)

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 proofing/sizing: 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 proofing/sizing upgrade is $45.00 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.

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 assembly you may add any of these upgrades to your shopping cart. Click here to add upgrades.

ARP-2000 rod bolts: This is one upgrade that we find to be very valuable. The rod bolts are most likely to fail under hard use, moreso than the rod itself. When a rod bolt fails during high RPM, total engine destruction is usually the result. The ARP-2000 rod bolts are a very good upgrade, in our opinion. We actually have few, if any, problems with the regular ARP-8740 bolts, but those who run hard always upgrade to the ARP-2000 rod bolts. The ARP-2000 rod bolts also torque at a higher number, and this increased clamping force is also a factor in keeping the big end of the rod stable and true to size. The ARP-2000 bolts are installed in the rods and this upgrade is only available with the Competition or H-beam rod upgrade.

Cost of this ARP 2000 rod bolt upgrade is $85.00 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.

Some of these upgrades 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. Pricing of upgrades subject to change.

BE SURE OF THE COMPRESSION RANGE AND BORE SIZE YOU WANT BEFORE PURCHASING.

A note from Skip White, company president.

We have built this setup for many people that are into serious street/strip use as well as drag racing, and have yet to experience a failure. Every part in this assembly meets our satisfaction. I can promise you that many assemblies offered by other sellers pale in comparison to ours. This is the best value you will find on the market.

Many people have asked how is it that we can sell this assembly for such a low price. To answer this; we buy our products at master WD (warehouse distributor) level for all of the items in this assembly, and we are selling direct to the public. We are a volume sales based company. Our profit is based on sheer volume, with a very low markup. By selling large volumes, we have to purchase large volumes of products. It is this large volume purchasing that allows us to buy products at a much lower price and we simply pass these savings on to our customers.
