When I was looking at these issues, I did the flow calculations to add a 
little engineering to the decision. For a 4 gpm flow of 20w-50 oil at 
212 degrees, the pressure drop is: 0.2, 0.5 and 2.0 psi/ft for AN10, 8 
and 6 respectively. Fittings and valves are usually treated as so many 
equivalent feet of straight pipe. I think 4 gpm is a respectable rate. I 
surfed all over the internet looking for pump rates, but could not find 
specs on an actual pump rate for any engine. Next time you buy a "high 
volume" oil pump ask for the rate and see what happens.
