Dude, he is not building a Top Fuel engine which operates at 200psi oil pressure. He is building a street motor with occasional track time. There is no need for anything above 20-30 @ idle and 40-50 psi @ cruising speed. A stock pump will get these numbers if all the bearing clearances are right. Your idea of more pressure is "cheap insurance" makes no sense.
