Mr. Hamilton
About 15 years ago we took a stock FE street pan with a 5 qt capacity attached a clear hose to the bottom then fixed it against the side of the pan so it pointed straight up. The engine had a Melling high volume pump in it. Then we put the motor on the dyno and ran it up to 5000 RPM. It took around 28 seconds for the
oil height to stabilize at less than 3/4" in the pan. Not nearly enough to sustain safe engine operation in any conditions. especially not around "G" loaded corners. We then installed a high capacity,deep, pan. A Milodon if memory serves correct. Did the same test. The
oil height stabilized at 3". I don't remember if we restricted
oil to the valve train but I know it had a juice cam in it. Anyway, the bottom line from what we gathered is don't run a high volume pump unless you have the oil capacity to match.
I hope this helps.
