The stock Chrysler 360 car oil pan (4 qt?) is a joke for a high performance motor. This is the pan I chose with the Milodon p/u and a 72HV pump. Should I stroke/boost this baby I'm ready for the added demands. But even as, is the stock pan/pump has got to be cavitating or running on the edge during launches, long pulls, hard turns. The P/U and the pump work great together, not sure about in a stock setup, but who is to argue with MOPAR and their testing, I don't think that they would fabricate results.
