I know there's alot of members on here way sharper than me, so maybe one of you can help me out with some math. I have a stock stroke 340, .030 over which is 4.070 bore, trying to figure the compression ratio. We have a 71 cc chamber, a .039 compressed gasket, a .016 positive deck piston which has a dome. The dome measures 11 cc, and the valve reliefs measure 9cc, can anyone help figure this? Thanks in advance!
