I was wondering if most class racers are using restricted pushrods to keep too much oil from accumulating in the top end. Back in the old days, we just put pipe cleaners in the pushrods and went racing. I reckin if you can get just the right combo of oil thickness and pushrod hole size, you can get enuff oil to the top, but also keep more in the pan, so that you could actually get by with a bit less oil. But hey, I'm no expert. It just sounds reasonable.

Ok.... I have way too much cash under my hood to try to squeeze a bit of ET out of...oil... I'll leave this to others. Frankly, I'd rather load up than blow up.
