Exactly what is included:
Dart SHP Windsor block 9.500 deck with Cleveland mains, (bored, honed, and decked). Scat 4340 fully forged crank, King HP main and rod bearings. Dart HP coated cam bearings. Scat competition series rods with ARP 7/16 cap screws, Wiseco forged 2618 aircraft race grade pistons, fully balanced in house. Pro Race brand damper, and HD flexplate included. Mahle file fit plasma moly, ductile rings 1.5 1.5 3.00mm size.
This short block kit will also include at no extra charge a Ford block parts kit from Dart. This kit has many of the much needed small parts such as pipe plugs, cam bearings, oil filter adaptor and much more. There are actually two kits that are included. The cost for these two kits is normally around $125.00 The part number for these kits are, Ford block parts kit #32000015, and #32940000.
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. You should always re-wash your block before assembly. This is to assure that the block is free of contaminants.
he Wiseco forged pistons are rated very high in the street/strip performance industry. They
are made using the 2618 aircraft alloy and 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.
Those types of 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, we only have to remove approx. .005-.010 off the deck surface of the block. Our goal is set the piston at 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. On our bbc engines, we actually leave the piston about .003 to .005 in the hole to allow for possible piston rock. Our sbc engines will have the pistons setting right at zero with the deck.
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 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.
Pictured below is the new Dart SHP block. This block is the absolute ultimate in quality, durability, and value.

This short block kit is not assembled. See our other listings for this in assembled form.
We also offer this setup in various bore and piston volume sizes. See our other listings.
We are often asked if the Dart SHP block is able to handle high horse power builds. Our answer is that if you're building this for street and strip applications, then this block will handle most any buildup you do. 800+ HP builds are not uncommon with this block. Durability and longevity with high horsepower builds are not a problem with this block. NOs, twin turbo, blower, high compression builds are also not a problem. You will also find this block used in many marine applications.
Pictured below is our Centroid cnc block machine. The machine stands nearly 10 feet tall and weighs approx. 6,000 lbs. A huge difference in what you see at most machine shops.
Pictured above is our Centroid DRX 750 at the SEMA show. All were impressed by this machine's performance. It would be fair to say this is one of the most advanced block blue printing machines on the market.
SCAT 4340 FORGED CRANKSHAFT & King HP bearings.
The Scat crankshaft is brand new, first line product. Beware of sellers offering no name cranks. We have seen many issues with the no-name cranks on the market. Best way to tell if a seller is offering a no-name crank or rods is the fact they don't mention the brand.
KING MAIN AND ROD BEARINGS INCLUDED.
Our choice of rods are the Scat Competition Series rods with ARP cap screws.
The Scat Competition Series rods are far superior to conventional Scat style I-beam rods.
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 high RPM. Notice the general appearance in the pictures. These rods do look impressive. The style is reminiscent of a steel billet rod.
The Scat Competition Series extreme duty I-beam rods with ARP 8740 cap screws are not to be mistaken by the model name, "Pro-Comp" These rods are made exclusively by Scat. The final finish work on both ends of the rods is performed in the USA by Scat Industries. We are now using these in all of our Stage 4 and 5 sbc engines. These engines are making up to 630hp. We also use the 6.385 version of these rods in our big block 540 engines, making approx. 700+hp.
If you do a google search on the Scat Pro-Comp, (Competition Series) rods, you will find a vast amount of info on many car forums. All of the info is 100% positive.
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.
PRO RACE BRAND DAMPER.
Pro Street Series, made by Pro Race Performance Products. Non S.F.I. internally balanced, (non-weighted)
We have noticed others using a low grade knockoff brand balancer. They are substandard in our opinion, not just in appearance, but they are usually out of spec from what we have seen. The timing marks were also poorly marked on some of the balancers we have came across. We know of several competitors using these balancers. The Pro-Race brand is a much better product in our opinion. We have used the Pro-Race line of dampers since 2005. Failures are few and far between.
HEAVY DUTY FLEXPLATE INCLUDED.
HEAVY DUTY FLEXPLATE. This flexplate will resist cracking and warpage, leading to imbalance in the engine. One good telltale in identifying a cheap 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. Our HD plates are either zinc dichromate or black powder coated. We would never use the thinner OE plate on any high performance assembly. We have noticed several sellers using the light duty flexplates with their assemblies.
We do offer this assembly with a manual flywheel. See our other listings. In most cases we do have both sizes, 157 and 164 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.
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.
You can easily replace your flexplate to an exact match, should you ever need it. You would have to send us your damaged plate to match it.
Due to the name similarity 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 user ID of skipwhite and the 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 a few years later. Fred White began competing against us even though our contract had a non-compete clause in it.
As our business grew, we opened a second, much larger warehouse and machine shop around 2011, located on Brookside Ln. in Kingsport TN. By putting heart and soul in this company, we have become the number one street rod engine builder in the nation.
Fred sold his shop to an investor in 2016 and the new owners continue to reap the benefits from this confusion between the two shops. This investor lacks any knowledge of this industry. They continue to use the White Performance & Machine name. Contrary to what is posted on their website, 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.
All in all, we have been in this business 16+ years. Skip White's passion has been owning and building street rods for 47 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.
The great pretenders continue capitalizing on our success due to the name similarity, but have been degrading our reputation. Recently, we have been getting calls nearly on a daily basis from people that now realize there are two shops in this town with very similar names. They complain of serious problems in getting their engines in a timely manner from them. They think they purchased their engine from us. Due to the confusion, there is 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. We have an "A+" rating with the Better Business Bureau, and they have an "F" rating. That may change in the future, but they have had the "F" rating for several years, and we have maintained our A+ rating for many years.
FAST FORWARD TO 2019...We have become the largest street rod engine builder 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 with a positive feedback score of well over 206,000 and growing, as compared to our competitor’s score of approximately 24,000.
Our engines are custom-built to our customers' specifications and are shipped in approx. 2-4 weeks, perhaps sooner, depending on the season. Our rotating assemblies usually ship out in about one week or less, and our heads ship in about a week or less.
Now you know the real story, and we hope this helps with the confusion.
