I was thinking the same thing,talking to some of the most respected engine builders in the country and Ford SVT people, they pretty much all agree that anything from 50 psi to 60 psi at full throttle is more than enough oil pressure for a SBF engine......

One engine builder that builds SBF engines for racing that have a 9,000 rpm rev limiter has his engines running no more than 65 psi at 9,000 rpms...

My race engine oil pressure was 60 psi at 7,000 rpms and that was at 220 to 240 degrees of oil temp during a 30 minute road race,ran 8 seasons like that on the same engine with zero problems....
