DME makes a pro pan, 1" and 1 1/2" billet pans. They do not make a 2" pan. Our reason for the DME pan has more to do with their swing pick up, which has a bearing inside. This is one of the only swing pickups we have seen that does not actually "leak" around the bearing, causing loss of oil pressure. Too many alternate versions of this type of pickup have caused engine failures - many are not around any more. The DME pan has been tested and used extensively with zero issues. And no - it does not cool the oil, that is not the purpose of an oil pan. And yes, the motor will still hold 4 quarts of oil with this pan . . .Would it not be better to use a 2" pan from DME to have more room for fitting and more oil?
