http://store.summitracing.com/partde...0&autoview=sku
i have this piston pieced in a 388" sbc and i am tryin to figure out how many cc's of dish it has. Ideally, im trying to figure out the compression ratio:
4.030 bore
3.800 stroke
.041 head gasket
64cc head
zero decked block
Thank you!!!!!!

The only way you can figure out the compression ratio is to cc the the piston dish with the valve reliefs. Because of the unknown dish dia. and the exact valve relief. Once you have cc'ed the piston you can use this site to get the static compression ratio.
