IMO, get a high volume pump and then manipulate the pressure to your liking w/ the spring. Either trim the spring or shim the cap out w/ an extra gasket or two to drop the pressure.

Dragula...like I've said before, you don't need a 12 quart pan to keep a hemi out of oil starvation. You need to control where the oil you have is going. Your last combo had an issue somewhere that was putting oil somewhere it shouldn't have and starved the vitals. Your big pump and 12 quart pan was a bandaid at best and even that didn't work did it? My 572" hemi has 7.5 quarts in it and survives just fine turning 7500 rpm. Same setup since 2006.
