What compression do I have? Part# inside
I have a 350, .30 over with TRW Forged pistons, if I gave you these numbers would you be able to tell me?
Either with a 64cc or 72cc head.
On the top of the piston it shows in a bigger font L2256
littler font 99295 .30

According to my reference, TRW L-2256 pistons are flat top, forged, with four valve reliefs (totalling about 5cc), so with a nominal compressed head gasket thickness of 0.039" and a deck height of -0.015" under 76cc heads, you static would be 8.76:1. The same parameters with 64cc heads would increase the static compression to 9.90:1.
If you want to run the numbers youself, download this worksheet:
