All kinds of custom piston folks out there. But my engine used a dive block and together with 6.8 chevy rods the pin couldn't go any higher without getting into the bottom ring, at about a 9 to 1 comp. ratio. Lots of stuff to measure here though, the deck height of the block, I.E. has the block been cut on (?), and other stuff. There is also a difference in piston pin heights between different piston manufactors at a given comp. ratio, so you will have to work with your supplier. Has your block been sonic checked? A 60 over block scares me. And the Keith Black Hypotech. pistons are a bit heavy for my tastes. Also I would look at the Edelbrock alloy heads as a cost effective way to build a better hot rod motor. As to cams, I'm a bit one sided on that with 385 engines. Comp cams is my choice, and I wouldn't look past the steel roller rockers they sell for 385's if you are building a street car. Good luck!
