Hopefully XR7 Dave will jump on here. Depending on what year your SC is and what year 5.0 you get you have to splice the harness into your SC if you wish to use the fuel injection. It can be done but I hear is a tad tricky. It helps if you get the donor motor from a TBird, or get a nice built motor but use the tbird oil pan, and intake manifolds along with the bird wiring harness and accessory brackets. Also if you switch to an electric fan it might be easier than using the fan clutch and stock fan, also you might gain a few hp from not having to spin a fan w/ the engine.
