I have a 7/84 pan it's shallower than my '85 pans. The pumps are not the same either. If you swap to the deeper '85-'86 pan then you will need the '85-'86 oil pump.pdupler said:Nope. 82-83 were ~1/2 inch shallower than the 84-85 oil pans. Oil pump pickups were different too.
let's say that I have an '83 5M-GE, and I'm thinking of swapping in a 7M-GTE. Will I be able to use my oil pan? Or will I need a different year
