Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
I am sorry that you have not been helped yet. I just came online and saw your question
Ok, so you are not wanting to go back with the 4.1L engine, correct?
The biggest questions are how much are you wanting to invest as any other engine will require new wiring harness, computer, mounts, and likely some customization of exhaust and cooling system to make it work.
You cant put a rwd engine in this fwd vehicle. engine and transmission wont mate up and too many other issues as well.
any engine other than a 4.1 from a mid 80s eldorado will require new harness and computer, engine mount modifications, exhaust modification and possibly transmission adaptor. It is dependent upon how much money and time you want to invest into the project as what direction you want to go in
