I use to think the same way as you Tom until I read an article about oil capacity, power and pressure.
In the article they ran dyno tests with the engine (SBC of course) at 4,5 and 6 quarts. It was a 5 quart capacity oil pan with no windage tray.
It made the made about 5 more HP at 4 qrts over 5 without any pressure problems. The motor lost over 10 HP at 6 qrts and they lost some oil pressure at higher rpm. They came to the conclusion that windage was causing the oil to foam and cause the power loss.
After reading that article I started running only 5 qrts in my 6 qrt milodon pan and I picked up about 1 mph trap speed and nearly .1 sec. I've been running this way for the last 3-4 years without any oil pressure change over that time so I would venture to guess that I'm not having any oil starvation problems.
