I have a 1996 mustang Gt that has a bad motor in it, I am going to be swapping it out with a low mileage complete engine from a 2004 both being romeo engines, I want to use as many of the new engine parts as possible with that being said what I am i looking at here? is my fuel system and wiring harness gonna plug and play? will i be able to use my original coil pack type ignition to simplify it some? I am pretty good with a wrench but just not sure how compatible this stuff is. Any help would be great
