i found a 91 xr7 in the pull a part with an intact 5.0L H.O. motor, and was wanting to build it and swap it for the 4.6 i have now, which i cant find any worthwhile mods for. guy who works for ford says id have to get custom motor and trans. mounts, plus the wiring harness; but if they have the same frame then i can use the mounts off the xr7. anyone want to shed some light on the situation? what should i do about the engine? or what i can do to my 4.6? any and all help is appreciated, thanks.
