340 oil pump

I agree with everything said. It also matters how much oil is in the pan to start with. Reason is some have stuck the oil pan dry at high rpm's with a HY pump but maybe the motor was a quart low to start with. Not everybody checks the oil each time they fill the gas tank up and if the motor does not burn oil or leak you should not have too but if it starts burning oil and you forget to keep the oil up a HV pump is more likely to run out of oil to pump. Cold oil does not drain back as fast but again not everybody waits till the motor is fully warm up before they get on it. Agree that bigger oil pan is the best idea but its too bad a 5 quart small block pan is hard too find. I see only stock 4 quarts or a deep 8 quart which you loose ground space.
