I just bought a complete '97 Explorer 5.0 to replace the 5.0 in my 89 Stang. I know about the heads and intake, but specifically what are the sizes of the Explorer parts and should I use all or a combination of the parts? I DO NOT want to do any reprogramming of MAFs or computers unless absolutely necessary. Should I use the Mustang engine sensors or will the Explorer sensors work with the Stang wiring? I'd really like all these questions answered without straying from the subject. Thanks!
