I just recieved a 1998 mustang engine with only 5000 miles on it. i was wandering what i would have to do to make this work in my 2000 mustang. i know it does not have the PI heads, i just want to put the engine in while i build the original engine. i know i would have to use the wiring from the 2000, also the coil packs from the 2000 since there is one for each cylinder and no plug wires. does anyone know what else i would have to do? is the computer the same? thanks everyone for all the help.
