No, I didnt do it. I bought the car in my signature instead, much cheeper and faster
I guess all you would really need is some 99+ 4V heads (04 Termi pref.) and coolant hoses and some odds and ends That reminds me, if you go that rout then make sure to put on the cooling mod BEFORE you install the heads. I still need to do it on mine but dread dropping the transmition to get up in there
Really though, if you can find a wrecked Mach or 99+ Cobra you could do it. Might find the heads for $2000 in good shape. Then you just get a 03-04 Cobra IC lower plenum and a twin screw, hood prolly wont fit though. Gonna need a cowl hood more then likely
