Compression ratio??
This is probably a stupid question, but you never know until you ask. My 79 vette has a 72 vette or truck 454 engine according to the stamped block code. It is not original and the motor has been modified. Now the question, is there anyway to guess or estimate the compression ratio without doing a teardown? if the bore and stroke are still original,,What should it read on a compression test?
