440 oil level

I say no way. You'll never suck the pan dry and overfilling will just beat the oil up. Ive heard that you actually only "need" 4 qts. The 5th is a precaution for production cars so they would still be fine if the masses were to run to the add 1qt line. Also heard of "some" stock class drags cars only running 4qts back in the day. I would stiil stay at the full line however.
