Unless you're running extremely loose oil clearances on all the bearings, the only thing a high volume oil pump does is puts a lot of unnecessary stress on the distributor drive gear. On the race engines we ran .0025-.003" bearing clearance to allow the engine to rev up quickly, so a high volume pump was necessary just to maintain normal hot engine oil pressure. Doing race stuff on a street engine is usually a foolish thing to do. We built those engines to produce lots of power for a very short time. A round track engine with 1K miles on it was an antique!
