Does anyone have a formula or software program to tell what my compression ratio will be, I am getting to different answers from people. It is a 72 454 block bored 40 over, with 69-70 L-34/L-35 CLOSED chamber oval port heads. These heads by my book are 101 cc chambers. I am also using forged FLAT top pistons. The block and heads are not milled, just slightly resurfaced. I believe the compression ratio will be somewhere around 9.0. Another source says these heads have a chamber size of 96.5 Any one suggest a reliable source.
Thanks for the help.
