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!
