Hey Randy how are you,remember we met last summer when you were out for a drive and spotted my bird at my parents place.For what its worth my 350 runs around 35-40 psi at idle with a mellings oil pump 20w50 brad penn oil.

I have read that all that is required is 10 lbs per thousand RPM..not sure if thats true.
I'm a hobbyist. Not a professional. Don't be hatin'!

Generally speaking, the "rule of thmb" of 10 lbs. per 1,000 RPM is okay, but not "in stone". Many small block run only 45-50 lbs., but rev well beyond 7,000.
At a "hot idle, in gear", one should have at least 20 lbs. It should "jump" to 60 lbs., before it reaches 2,000.

How fresh is the motor, I would not run synthetic untill it is well broken in. Also synthetic will show less pressure, but more volume.
