Not needed....
This response doesn't answer the OP question, so please allow me. I've had a high volume Melling oil pump in 2 different engines. I believe there are 2 numbers, 10295, and 10296? Don't remember which is which. The high volume body and gerotor assembly is wider/thicker by around 3/16"-1/4" when compared to standard. I currently am running a wet sump LS7 in a C5. The block has piston oil squirters, so the demand for oil is high. I have run this pump in two different 427s, and NEVER pumped the pan dry. Of course I've never run at Bonneville or any airport top speed contest, either. Mainly because of the oil squirters, I did space the high volume oil pump relief spring about 1/8"-3/16" stiffer than stock. I've yet to pump the pan dry at the 617hp@crank level. OP, why do you believe you're pumping the pan dry?

In your application would not a high volume pump been the choice as opposed to high pressure? My guess is that OP doesn't have a clue about oil pumps period. Just something he's read or something that was said by a friend of his sitting around the car in the garage
