Hello, I'm considering having a new engine installed in my '97 4.6 'Bird. My current one has 165k wonderful miles. I would love to have a GT spec 4.6. I have neither the time or know how to do the swap myself. Can the GT spec engine work with my car. I think it should, but there's bound to be some kind of pitfall. Would the dealer make this swap? Would I be better served getting a standard motor and getting a custom chip for the cpu?
