Once again I find myself back at Corvette Action Center after searching the net and several small block Chevy motor books that yield only vague answers to my questions. Here is my current dilema. I am reassemblying my 283 motor and everything is going well after a few minor setbacks. I have installed my flat top pistons and crank and decided to check my piston to deck height. After taking several readings with several crank rotations I am finding my deck height to average between .034 - .039. on all eight cylinders. This block had a minimal resurfacing removing only enough to clean it up. Most of what I read in tech books seems to indicate that between .008 - .025 is the norm. I am concerned about this and how it affects my static compresson ratio. I believe my heads were resurfaced too but this was done before I bought the 61 Vette and I can't verify how much was taken off. I am trying to decide what kind of head gasket to use and what the proper crush would be for this situation. The heads are 462's (not original and not hardened seats) and the chamber size new is 64cc. I'm not building a race car and I just want to match the original compression ratio for a 270HP motor which I believe is 9.5:1. Right now I am guessing I would have about 8.5:1 with a .039 crush gasket. I'll thank you in advance for any help as well as for your expert help in the past.
