YY1 is totally right! I kept my original 904 for the time being just cause I didn't want to deal with totally dissecting and modifying the car - maybe later.You will need an LA style 360 oil pan - as far as I know they don't make a center sump for the magnum engines. You will also have to use the center sump oil pump pickup. You can use the newer style oil pan gaskets but you need to do some modifications - there is a gap in the front corners when using the new gasket. There are threads on here where guys did some welding and modified the LA pan to match the magnum pan. I used the circular LA rubber gaskets for the centers and cut the magnum gasket for the sides.I bought my oil pan from Jeg's, best price I found for aftermarket pans. I drilled holes in the circular center section of the pan for the nibs on the LA gasket to go through. Guess I could have just cut the nibs off. Good Luck.
