Offroad-Express

does anyone know some one or a company that does a kit to run a 96 xr8 5.0 4stage auto with the factory ecu. i want to put one in a 58 ranchero ,and if works well might be a option for my buggy/club thing im building(very slowly). a bit heavier than the ls1 but a shit load cheaper ,cheers.
