I own a 1979 Firebird Formula that has a 4.9L v8 engine and is automatic. The engine has well over 300000 km's on it, and it is running terribly - so I decided to replace the engine. I found a friend's 1985 Buick Regal Limited that has a 5.0L V8 and is automatic also - he is selling me the engine because it works fine, but the transmission is shot. We took the 5.0L out of the Regal, and took the transmission off (since we're using the transmission in my firebird.) However, we seem to be worried about the difference in electical components. I was told that the transmission would fit (between my car and the buick's engine) and the mounts would fit, and everything would be fine.. but then we noticed that there are a lot of wires leading into the car from the engine in the Buicks, and the Firebird's engine is less cluttered, it does not have nearly the amount of wiring. Before we attempt to finalize this project, we would like to know how vital all of the tiny wiring is on the Regal. Are these all fancy sensors unneccsary to performance, or are these vital to performance/operation? Would we have to do something like take the wiring harness out of the regal and somehow splice it into the Firebird? Thank you for your help, I can give you more specifics if the situation isn't clear enough Matthew Housser
