The stock FD oil system makes over 68psi pressure. It all depends at what rpms you do the tests. In fact it normally will make over 90psi above 4000 rpm.

I did some easy mechanical common sense mods to my oil system to improve oil flow.
This mainly was cleaning up and slightly reshaping the oil pump cavities in the front housing where the pump sits and where the oil comes out. Then I matched up the oil input holes in the stat gears to the oil passages in the rear and front housings.
This along with the PineApple e-shaft washer mod, new rear regulator, new pump, and shimmed front regualtor, my pressure runs about 110psi with the racing oil jets.

I have friends who used the stock oil jets with the ball and spring removed, and their pressure is OK, but not as good as mine.
