3700 0r 3.7 compression
« on: November 16, 2015, 07:49:01 pm »
How much compression can either the 3700 or 3.7 handle before they develop a power loss or no noticeable gain. Right now I have my 3.7 at 166 PSI with about .022 squish. Should I just leave the PSI alone to make room for playing around with advancing the timing?
