Rick, I am by no means an engine expert but everthing I have read and heard lately is that the 10 lbs. for every 1,000 rpms is old school engine thinking.
I know that the Clevelands and the FE's because of their poor oiling systems need lots of
oil pressure to insure
oil is getting throughout the engine.
I read where the Nascar cup guys will actually lower thier
oil pressure for qualifing down to 25 psi and then raise it up to 35 psi for race conditions. Or course they rebuild after each race so those numbers might not work for longevity on the street.
In my 408 Dart which has the best oiling system of any Ford block, I run about 45 psi at 7,000 rpms running 20-50 dyno oil. Im gonna go to 10-40
synthetic this year as I now have about seated the rings.
I think you oil pressure is just fine.
