    Provided you get a motor that's the same OBD version as yours, you should be fine. I think 94 is still OBD-I, which only has a couple sensors on the head. If it's OBD-II, it'll have a bunch more sensors and the sensors will be on the heads and the block.

    Anywhere between 87-95 should work fine for you, just save your original intake and throttle body to be on the safe side.
