The way I have my engine figured is 3.905 bore, 3.622 stroke, .040 gasket and a deck of -.012, -26cc pistons, with 64cc heads. That yeilds a C/R of roughy 8.4:1. I am going for a cheap 347ci engine with stock heads. I plan on doing a ST80 turbo at 14 lbs of boost. Its gonna be a street car so I want it safe.

ohio crank shaft did them for me, which is a engine machine shop that was close to me, the pistons were JE, dont think they took off to much, just milled them down a hair.

Mine are -2cc and I need them to be between -20 and -18cc. I don't know if they can be cut that much or not. Maybe I should call diamond? They aren't all that great about answering the phone so anyone have any other suggestions?
