Thats more like it. On one of your other threads you registered 185 PSI witch I felt was high for your combo. IMO with around 10.25 Comp and that 262* cam your 170-175 PSI is in the normal range for the combo. Maybe even a little high.

But, FWIW, the Calulater that Dodgem posted was Happy about by 20# PSI for my Combo. But with your engine specs, it was almost right on. mike
