Hey Guys,
I just got back my new 383 for my 69 RR from my engine builder. I told him I wanted a streetable engine that had 400-450 HP. He put a comp cams roller XR286HR in it. It has edelbrock rpm heads, the whole thing was done. He put a high volume oil pump in it, my question is do I need one or can I use a regular oil pump? Doesn't a high volume pump need special oil pan and other stuff? It has the stock oil pan. I'm thinking it will suck all the oil out of the pan? Thanks!
A high volume pump at 60 psi is not pumping any more oil to the bearings than a standard pump at 60 psi in the same motor. The high volume pump just adds stress to the parts, and additional heat to the oil.
Only if you cannot maintain adequate oil pressure with a standard pump should you move to a high volume pump.
