SBC's and BBC's have excellent oiling systems. A standard pump with a GOOD filter, such as a NAPA Gold, and quality synthetic oil, should get you all of the oil pressure you need. That old saying of 10lbs of pressure for every 1000rpm holds true. Anything over that and you are sucking extra hp to drive the pump. I had an old sbc with a high volume pump and on a cold start it would shoot up to well over what the gauge would read, lol. Gauge went to 80 iirc. At a hot idle at 850rpm it would have 40lbs. I thought it was awesome, lol. Little did I know I was losing power.
