Compression Ratio is defined as the ratio of combustion chamber volume to the SUM of C.C. volume + the swept cylinder volume. Here's my problem:
Guy has a 4.6, stock bore and stroke, 43cc combustion chamber volume. 4.6 is 4600cc, take 1 cylinder,
4600/8 = 575cc swept volume. C.R. works out to 575 + 43 divided by 43 = 14.4. His head supplier claims 10.1.
Where am I going wrong? imp
