    Question Compression..lookin' for a math whiz

     



    Is there a formula for figuring your compression ratio? Let's say I have an engine with a 3.736 bore & 3.48 stroke with flat top pistons and I know that this engine with 58cc heads will have 10:1 compression. What will my compression be if I used heads with a 64cc, 70cc or a 72cc chamber? I would appreciate any help.
