Bob,

That's a GREAT point with the Hemis and it really amazes me how much oil (quantity) meters through a motor during a full throttle pass.

The hemi head has (I'm guessing) probably more than twice the oil coated surface area for oil to collect up top and drainback to the sump is far more of an issue, so it's logical that the more oil that is (for want of a better word) "dwelling" on an engine surface and not draining immediately to the pan has to be made up for in the system volume.

It hasn't been mentioned here but Oil flow is also a critical cooling component as it wicks away heat from all of the engine surfaces, and on a drag car the valve springs particularly.

FWIW, Bob's tip of run the HV and an extra quart was the way we used to do it 30+ years ago and I never lost a bottom end to oil related failures, even at 8200 rpm in a W2 340 which was wound pretty tight for a street motor in the late 70's-early 80's. And the front sump design of the Typical A,B, E bodies didn't help things either!
