I have done several modifications to my 96 Mustang GTR. It is not all together easy working on these cars but they will definitely reward you in the long run. I started off with a Hurst short throw shifter. Then I went on to the taillight ,carbon fiber from APC and a 99 Cobra T45. After a period of complacency I installed cold air intake, followed by low restriction side exiting exhaust. Then about a year or so later I bolted on drilled and slotted rotors just before preformed the PI swap. Which brought port and polished Windsor SOHC heads and FRPP cams along with FRPP intake manifold. Now I have completely rebuilt the old engine with an all forged steel rotating assembly stroker kit. I also bolted on some long tube headers, king cobra clutch, Mach 1 pedals, new carpet and racing seats.
    So if you need any help or advice on a 4.6L SOHC&DOHC Ford engine I'll be glad to help.
