Do not confuse a "compression test" (cylinder pressure) with overall compression........Cam overlap has a lot to do with cylinder pressure at low rpms,I've seen one 351-W with 10.5 to 1 calculated compression,run 120 psi on each cylinder in a "compression test",doing the
oil sqirt in each cylinder gave NO higher reading,leak down test showed everything was sealing and within specs,cam had a lot of overlap and at low rpm cranking did not show a lot of cylinder pressure,motor runs fine and goes like hell........
If your compression test per cylinder is within 5 to 10% of each other that is good,if you use the
oil sqirt test and gain nothing,then the rings are good,if you do a leak down test and everything shows good,then the valves are sealing and that is good.....if it runs good,then I would not worry too much about it,run it for a while and see how you like it before going in the motor........
