Bought a 422 short block about a year ago and has these pistons from diamond in it. Anybody got an idea what kinda compresion this would have with say a 65cc head zero deck block.? Any head suggestions? E85 street strip car. Fi tech fuel injection.
 
I am by no means an expert... but the Summit calculator (I know there's many of them calculators) says 11.1:1-ish.
