New ls ky
I do know it pretty easy to wire up a stock harness so u can go fuel injection just not as clean looking as a carb set up. Ive owned fox mustangs forever lol and if this 5.3 swap goes good in this ole fire chicken then im gonna do one in a 85 mustang coupe body i got. Good luck with the build and if u need any parts just get with me cause i know i will have some left over lol
