Re: Compression Test 1976 305

I know very little about compression, but the #'s look OK to me. Looks like even wear on all cylinders. IIRC, ideal is 150 PSI with 10% or less variation between all cylinders, which you have. Your rings are probably showing a little wear.

I can't comment on the cold vs. warm engine testing.
