Rodknock Nothing against 767 Jockey but his builder is not the smartest crayon in the box. ordering parts, (CUSTOM) before you have a block in which to install the parts is not the way to build anything.
An oversize set of pistons cause alot of problem with this too start. Someone tryed to skin the cat and it didn't work out. 767Jockey should have gone with a big bore Shelby block and called it a day. I have heard very few problems with Ponds and Genesis block. waiting to get them seams to be the big problem. As far as any build the block should be gone through from front to back and each channel and gallery should be cleaned and bushed in a hot tank before even starting a build. The fact of overboring a new motor to the max is not something I would ever do and don't understand this kind of thinking.
