I just poured the combustion chamber on a C6AE-U head that I removed from a 1966 Galaxie with the original 390 2-barrel engine. Without cleaning any carbon from the chamber, it poured 78.0 cc's. That means it could have read as much as 79 or more if the heads had been cleaned. So much for Ford's advertised engine specs.
I have almost always found that the specs Ford gives on combustion chambers are nowhere near as large as the cc's on heads that actually come off of original engines. Use the Ford specs if you want to for reference but be sure to actually measure the cc's before putting an engine together if you are looking for actual compression ratios. You will be surprised how far off the numbers actually are. |
