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 Pro-Sport SFI 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.

Rust warning.

If you are going to store your rotating assembly or short block kit for any length of time, it is very important that you protect these parts by spraying a light coat of rust preventive substance on all bare metal parts. This is especially important for those storing these parts in a high moisture or humid environment. Very light surface rust is easily removable and will cause no harm, but heavy rust can damage these parts and be very costly to fix.

Our thoughts on what the competition has to offer.

Many rotating assemblies 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 assembly. The failure rate with the parts used in our assembly 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 assemblies that include parts that have high failure rates. Many of these parts also pose a great problem with assembly 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. Such is the case with 4 valve relief pistons. Those type pistons are sure to not clear the valves when using any decent sized cam. 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 the assembly 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 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.

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.

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 $39.50 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.  

   

Rod to cam clearance and sizing: We know exactly where and how much to cut the rods on our vertical milling machine for correct cam clearance, and 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 to cam clearancing and 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. Before you finalize your purchase of this assembly you may add any of these upgrades to your shopping cart. 

We do the rod to cam clearancing on a vertical milling machine as pictured below as part of this upgrade. By doing this procedure on a milling machine the rods are cut precisely at the correct angle to clear the cam. This also keeps the amount removed identical on each rod. It would be very difficult to do this by hand on a grinder as is commonly done. After we clearance the rods on the milling machine we go over them on a wire brush machine to clean up the edges, and remove any stress risers. This is a very critical procedure. Those who lack the experience and choose to do this on their own risk destroying the rod and or the bolt, or at least removing too much material and weakening the rod and or bolt.

  

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.  

SCAT H-BEAM RODS WITH ARP 2000 BOLT: Recommended for those running hard. The Scat Competition rods that come with this assembly are sufficient for most street rod uses, but the Scat H-Beam series rods offer more security against rod breakage under hard use, and they have the huge ARP-2000 7/16’s cap screws. The scat h-beam rods with the ARP 2000 rod bolts have an 800+ Hp rating, and the slight cost to upgrade is well worth it in our opinion. The cost of this upgrade is $150.00.

MANLEY PRO SERIES 4340 Forged Crank: The Manley Pro Series  forged crank is a top tier rated product and 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 in many of our assemblies in our other listings. 

Cost of this forged crank upgrade is $685.00 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.  

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 note from Skip White, company president.

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. 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. This is our main competitive edge.

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.
