I know that this will be a very basic and common knowledge question for the majority of you all. I have no experience with Mustangs until this one. At the risk of asking a stupid question....... Other than the heads and intake, are there any other differences in a 94 GT 5.0 and a 5.0 from an Explorer? I know, I know..... dumb question right? I ask because I do not know for sure, and I can buy the whole engine from a wrecked Explorer for $600 here, so I thought it migh be easier to just get the engine instead of trying to get just heads and the intake for my engine (which is on an engine stand now). Also, will the wiring harness from my engine plug right into the Explorer engine, or will I need to modify it? Thanks!
