i got a 86 coupe roller from a friend and it orig. had a 6cyl fuel inj in it. i just bought a 93 5.0 motor for it complete minus the wire harness. my question is whta all will i need to change to keep it fuel inj. i know a wire harness for a v8 fuel inj. and comp . but what year do i get those from. i just want to keep it fuel inj. if it is to much work and money i will just go what a carb set up. any help will be awesome. thanks. i have done some research but just find 4 cyl to 5.0. i just know that the 6cyl harness wont work as it is missing 2 inj. and the comp isn't the same. just dont know what year to get the stuff out of to make it work.
