We took a lot of them out, that were blown up and replaced them with 3208s in the day. Need an adapter to go from SAE 2 to SAE 3 bell housing. I don't even know were you would come up with parts for a 504. They were a high reving motor, and so were the 3208s. About the only engine you can replace them with, with out changing your gearing.
Cummins 504
