Isn't a '89 fuel injected in some way? if in California that will be a smog nightmare or any other state that has smog tests. If so check with the state you are in on engine swaps before finding out you will have to undo all your work.
If swapping a V8 with a V8 then I would think it is all the same mount wise and you will just have to figure how to plumb the carb and igntion.
Yah i think they are fuel injected, i think you will have difficulty with a carburated engine on ur car in Cali. Well as long as u have maintnance on it, u should probably be ok.
