Trying to see what my compression ratio is. I still need to cc the 360 heads that are on it they are the 596 heads. At TDC I used a few stacked feeler gauges and a straight edge and I’m coming up with pistons close to 0.100 in the hole. Using the online calc and guessing at 70cc combustion chamber and approx 3 cc for the 4 valve reliefs in the pistons I come up with 7.3:1. Is that typical of 80’s 318’s? I thought 7.5:1 at the very least. Anyone know how thick stock headgaskets were?...
80’s 318 compression ratio figuring out where I’m at.
