HV oil pump vs Stock oil pan

I never did much wrenching on big equipment diesels, but, in the 40+ years of working on car/pickup gasoline engines, I NEVER had an engine with 10psi at idle that had all good internals. There was always something out of specs....be it oil pump, mains, rods, cam bearings, etc. This includes some freshly rebuilt engines where the crank grind didn't match the bearing size, and various assembly screwups.
