Re: how much oil pressure is to much
And since oil pressure is just an indirect measurement of how much oil leaks past your bearings, bearing clearances have a huge impact. My own 1989 302 with 10W-30 oil is 55 psi cold, 35-40 psi hot, at 2000 rpm where the Ford service manuals used to tell you to check at.
70 Maverick Grabber, 5.0 (Perf. RPM heads, RPM intake, FiTech EFI, Comp XE266HR roller cam, EDIS/Megajolt ignition, long headers), T5Z w/Steeda TriAx shifter, 9" Trac Loc w/3.89:1, 31 spline axles.
