Can anyone walk me through calculating compression ratio with different pistons? Im chair flying a few options and would like to see what piston will put me at 10-10.5: 1 on a .030 318. I've tossed around heads from aerohead racing, mostly because of ease and cost. 68-70cc open chamber, 160cc intake port volume. 1.88x1.60 valves. Any input would be great, just never been too savvy with the numbers. Thanks guys! Glad to be back.
