dish vs flat

According to JE pistons with a 350 block. The dished piston is 8.5 to 1 compression and the flat top is 10.4 to 1 compression. At a .020 bore.

One MAJOR detail has been left out, how big is the dish? This will make all the difference in the world.

If you are trying to figure out your compression ratio you need to know your stroke, rod length (to firgue out which piston), bore, head chamber cc, head gasket specs, and how far in the hole the poiston is at TDC (top dead center).
