That's what I'm wondering. I'm planning on putting all the 87 FI, intake, exhaust and other stuff onto the 94 long block. I just need to know if it would work. I know there can be unseen differences, like on Saturns: The 91 and 92 Saturn engines cannot be swapped into a later car or later engine swapped into an 91 or 92 Saturn simply because the crank reluctor ring is different. Any such differences here?
