Well, my car has been burning oil for a while now and this summer something is going to be done about it.. I just stumbled upon a built up cobra 5.0, supposedly made 275hp at the rear wheels when it was in a mustang. The owner is asking $1200 which may be negotiable. There's nothing wrong with the engine, it's been torn down and checked out since it was removed from the car. I'm guessing this is a dumb question, but would I be better off to just buy the cobra engine and forget about rebuilding my non-GT40 5.0? Also, if I were to run that cobra engine, would I need to get a cobra computer, or is that unnecessary? Thanks
