High Volume Oil Pump VS Standard Oil Pump

I run a std pump but with the HP spring from MP. You can also shim the stock spring. With the right clearances, oil pressure should peak around 65-70psi witht he std pump and HP spring. The HV pump moves a lot more oil, but as said, really takes a lot of power to run, and builds heat in the oil you dont want. The "sucking the pan dry" comes from hard launches and stock unbaffled small block pans, and HV pumps with poor oil drain back. If you have no windage corntrol, and you pump a ton of oil into the top, it has to get back somehow, and it has to go by the crank. So a ton of oil gets caught with the crank as it drains past. I smooth out drainback holes, and always run some sort of windage control. Then the stock pans are fine.
