Our custom made Wiseco pistons are rated very high in the street/strip performance industry. Wiseco normally offer several grades of pistons, starting with the lower grade 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 and have fully machined crowns rather than the as cast crowns that are on the Pro-Tru series. Our Wiseco pistons are custom made for us, and have both of these premium features, 2618 Alloy, and fully machined crowns. All premium grade forged pistons on the market have these two unique features and usually cost around $800-$1100 per set.

Important note

Many customers have asked us what size they should bore their block at to allow for a proper piston to wall clearance. The required clearance is built into the piston already. For example if these pistons show a given size such as 4.030 then that is exactly what you will bore the block to. The actual size of the pistons when measured at the skirt, 1/2 inch above the tang will show to be approx. 4.026. The needed clearance is built in. Should you be using these pistons in a marine app. where the boat receives it's water from the lake, then an additional 1.5-2.0 thous. would be added to your final bore size, and some forced induction apps may also require a slight increase in bore size.

These pistons are totally suitable for use with mid level nitrous or blower setups. Extreme level builds that are making hp numbers in the 1000 hp range will require a set of custom made extreme duty pistons.

You may have noticed that our Wiseco custom made 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 certain high performance applications as well as for street rod use. These pistons are 100% suitable for street or strip use. A true all out racing piston would not be suitable for street use for many reasons, but these pistons are perfectly designed for use on the street, as well as medium to upper level drag racing.

We do our own balancing with our brand new, 2013 model CWT 5500 Series Balancer, which replaced our 2011 Hines Legend balancer. The CWT 5500 is the absolute ultimate for precision balancing. When we balance the assembly, it will be to very high specs., usually plus or minus 1-2 grams. We include a balance sheet with your setup.

Our custom made Wiseco forged pistons are made from 2618 aircraft alloy, and are capable of handling far more hp than a cast or hypereutectic piston. We find this alloy to be much more suitable for high performance engines than the common 4032 forged alloy that many others offer. 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 it can cause severe damage to your engine. The 2618 forged piston is able to withstand the 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.

These pistons are also suitable for use with nitrous or blower setups, but for those not running forced induction, the forged pistons offer very high reliability. The 2618 forged piston is far stronger than hypereutectic pistons. For the slight increase in cost, this setup is the best value on the market.

We would not even consider using Speed Pro, Keith Black (KB), or any brand of hypereutectic pistons due to the possible fragmentation that could occur during detonation. If you're in doubt about this, do an internet search on the subject. Forged pistons are far superior to cast or hypereutectic pistons in many ways, especially our custom made Wiseco pistons made from 2618 aircraft alloy.

Having high quality forged pistons will be your only hope should the conditions arise for detonation to occur. We sell nothing but forged pistons, as I find it comforting to know that my customers will have an engine with a tremendous safeguard built into it. Support rails, wrist pins, and pin locks included.

HASTINGS 2M SERIES MOLY RINGS

Prefit Drop-In - Hastings Original Moly Ring Set - 5/64, 5/64, 3/16

Manufacturer: Hastings Mfg

Part #: 2M 683

Hastings quality piston rings are a perfect replacement for the stock or medium performance build up. Featuring Chrome moly ductile iron top rings, cast iron reverse taper second rings and Hastings famous Flex-vent oil control rings, Hastings ring sets feature standard ring end gaps for easy installation.

We offer premium grade Ram brand SFI Billet Steel flywheels for manual transmission use at an additional cost. See our other listings. This assembly includes a flexplate for automatic transmission use at no additional cost.

When choosing a flywheel for manual transmission use, be sure to know what tooth count you need. There are two sizes available, and it is of the utmost importance to select the flywheel that is correct for this assembly. There are several factors that must be addressed when choosing your correct flywheel. The tooth count must be correct. This is very important. There are two sizes available, and it is the bellhousing size on the transmission that determines this. Another important factor is if the assembly your purchasing is internally balanced often referred to as neutral balanced or if it is an externally balanced assembly, often referred to as externally balanced. All of our assembly ads will have this information in them. Big block and small block engines will also have a different bolt pattern in most cases. To sum it up, there are three important factors to look for when selecting the correct flywheel, tooth count, int. or ext bal. and whether or not you have a big block or small block engine. The Ram brand flywheels we offer are very high quality.

We include a Pro-Race brand damper and heavy duty race grade flexplate with your assembly.

When you receive your Pro Race brand damper, you will notice the appearance to be of the best you will ever see. We carry most of the Pro Race line, and consider them a first rate product, for the lowest cost you will find. All this may sound like nothing more than a sales pitch, and I suppose it is, but heed our warning about the low quality dampers on the market. The price will be the best indicator. They may be marketed under several names, or no name at all, are often painted black, and they are of very low quality.

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.

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 $24.50 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 assembly you may add any of these upgrades to your shopping cart.

On occasion we are unable to obtain the Pioneer brand SFI flexplate and will substitute it for the Scat SFI brand plate pictured below. The quality is equal in every aspect.

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.

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.

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.

Rod sizing: All new rods, regardless of brand, must 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. This upgrade is a must for those building their engine without the services of a machine shop.

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.

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, more so 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 rod upgrade. Cost is $89.50

Scat or Eagle 4340 Forged Crank: The forged Scat crank has a rating of 800+ HP. This is the ultimate upgrade for those wanting to run hard. Nos, blowers, turbos, are not an issue with this crank. Even without such power adders, this Crank offers great protection under the most severe conditions. This upgrade also comes with the high Performance King bearings. Should you decide to run power adders in the future, this would be essential. The fatigue life of the 4340 crank over the cast nodular is also greatly extended. We do offer this upgrade as part of many of our assemblies in our other listings. They have the key words, "fully forged," in the title.

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.

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.

Skip White

We are not responsible for collateral damage caused by the use of this product. 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 two 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 or Marine or any other similar name. Many customers looking for us online inadvertently find them, thinking we are the same company. Definitely not...there is no connection between the two companies. We don't have a problem with free enterprise (competition). However, when the competition builds their foundation on such things as a name similarity and their supposedly long history of being in business, then we think it's about time we set the record straight. We have owned White Performance since 2003, with the exception of the machine shop, which was owned by Fred White at the time. He continued to operate the machine shop and build engines for us while we continued selling online under the eBay user ID of skipwhite and the eBay store name of whiteperformance1. Due to their limited production capability and many disagreements about the engine building process and workmanship, we opted to open a full scale machine shop of our own. Fred White began competing against us even though our contract had a no compete clause in it. Fred White sold his machine shop in 2016. As our business grew over the years, we expanded our operation, and have become the number one street rod engine building in the nation. Due to the name similarity, many people looking for us mistakenly contacted Fred's shop. The problem continues to this day and the new owners of Fred's shop reap the benefits from this confusion between the two shops. Fortunately we stay plenty busy throughout the year, but a new problem has come up. We’re getting calls nearly on a daily basis from people that realize there are two shops in this town with very similar names and complain of serious problems in getting their engine in a timely manner from them. They think they purchased their engine or rotating assembly from us. Due to the confusion, there was an increasing amount of negative talk that is starting to reflect on our reputation within the street rod community, when in fact we have a near perfect reputation in this industry. All in all, we have been in this business for going on 21 years. By putting heart and soul in this company, we have become the number one street rod engine builder in the country. Skip White's passion has been owning and building street rods for 51 years on a personal level. The knowledge he has gained over time has allowed him to venture into this business and succeed to a very high level. As mentioned above Fred White sold his machine shop to an investor in early 2016. This investor lacks any knowledge of this industry. They continue to use the White Performance & Machine name. Fred White is no longer associated with the company in any way. Their main spiel in advertising is, "In business since 1979," when in fact, we purchased the White Performance company in 2003, with the exception of the machine shop. The great pretenders continued capitalizing from our success, but as mentioned, have been degrading our reputation. (Update, The people that took over Fred Whites machine shop are no longer in business as of the past couple years.) FAST FORWARD TO 2023...We have become the largest street rod engine builder and supplier of rotating assemblies in the nation. Our engines, rotating assemblies, and cylinder heads are built to very high standards and shipped to our customers in a timely manner. We are a premier seller on eBay with a positive feedback score of well over 212,000. Our engines are custom-built to our customers' specifications and are shipped, in general, in 2-5 weeks, perhaps sooner, depending on the season. Our rotating assemblies ship out in about one week, and our heads ship in about a week or less. Now you know the real story, and we hope this helps with the confusion.
