IIRC the pan fitment is the same but you use the mag gasket with the 5.2/5.9 & an LA gasket with a 360. Spend some time makeing sure the front/rear black seals are fitted dead on especially the front one & some pans (more of an aftermarket issue) have a shallower "halfmoon" & the flat ends of the front black seal may need to be shortened a bit & sometimes the side gaskets need to be "sectioned" so the bolt holes are dead on and the 4 corner mini pieces can need trimming.the thin rear black seal may be a bit too long & need sectioned then some good cement at that junction. As you know oil leaks are the cats' ass/worth the prep/trouble.
