HV oil pump vs Stock oil pan

If you want to add more pressure, the HV pump is not the way to do it. Get the MP high pressure spring and put it in the pump you have. But 15 PSI at 800 RPM hot is plenty. If you don't think it is, unscrew the filter while it's running.

agree , I have about 18-19 on hot running 505'' wedge at 1100 rpm...goes up with rpm tho...
