    Kyle, Are you saying that your compression gauge is giving you a reading of 60 psi on both holes of your 1972 40 horse? Someone will correct me if I’m off base but I believe that motor should be about twice that. If that’s the case them maybe your 5.5s were and are actually are at 60-70psi which isn’t out of the ballpark at all for these. They’ll certainly run at that pressure. My next step would be a leak down test and verify piston orientation.
