1qt oil per 1,000 RPM works for me
kind of like the old 10 psi per 1,000 RPM rule of thumb.

I ran the 451 stroker at the full line the first few years I raced it. I think that was with about 7+qts of oil? I later ran it with just 6 qts and picked up some power and ET. I ran the engine like that for about eight years with no oil problems. This was shifting at around 6,300 RPM.
