Dunno, but if you have flat pistons and they're level with the top of the block, then what ever the size of the combustion chamber is + h/g will determine your CR.

well my pistens have a rased bit in the middle of them but im not sure if the lower compresstion ones are flat or rased witch it would be good if somone who knows could discribe them/post a pic of one

is the dome on the piston offset? is the combustion chamber basic Hemi shape or is it more detailed.

The piston with a dome in the center is the older type ( i think higher compression) piston with offset dome ( i think is lower compression) i have it written down at hom ill check thisafternoon for you.
