Lets back up and take a breather for a moment.
We were trying to work with Dave Everhart,HP Performance and early on there was some design issues and they made some changes to improve and strengthen the block.There are a couple of versions one suited for street and stip and another version for all out race engines.The Race block was to be of raised cam design and have 1/2" head bolts and 1/2" cross main bolts as well a 9/16" main cap bolts.
Due to casting availability at the foundary both blocks were held back from production.Some of the casting recieved and sent for machining were dilivered to HP with machining errors which caused another setback.Finally after much time,effort and aggravation HP got a number of blocks that were sale ready.The waiting list exceeded the finished blocks produced and the first batches were of the street/strip varity.We haven't talked to Dave recently to find if finished blocks are available,but from our conversations and what we seen at the diffrent shows they certainly seem to be a quality product.Like any new products we are certain there maybe a few issues that need attention but that's why we take the products to machinist and engine builders if we can't correct them ourselves.We don't care who product it is it must be checked and if need be corrected.If everything was perfect and we lived in a perfect world the engine would assemble it's self.A lot of issue we here about are so minor and easily corrected it ain't worth gripping about.We understand also that if there are major issues like some had incountered with the small block, blocks we would hope that they would be detailed and shared with others before a lot of time and money was wasted.
