I also used a crank scraper fitted to the edge of the block & a windage tray to help keep oil in the pan. The pan was fitted with a larger sump area & trap doors to keep oil near the pick-up.
I ran 60 psi oil pressure max, ran Castrol 20w50 for break-in, changed to Mobil One 15w50 after one week. Never had a oil-pressure related failure. Keep in mind this was a hand built, balanced & blue-printed engine. Nothing was left as the factory made it.
There is definetely HP to be gained by controlling what happens in the crankcase.
