    First thing though, mustsng motor mounts don't work with the stock k-member. I would probably swap to a tubular unit for more clearance, adjustability and to use stang mounts.

    Wiring will have to be taken from either a donor car or wired up using a stand alone aftermarket job.

    Everything else should pretty much go right in.
    Ive dropped an adjustable k-member in from lmr, so thats taken care of. Also, the 4.6 and trans will be coming out of my '08 p71, the rear axle busted and figured i could just use that beast for the donor. I have the wiring and everything. Also, both the engine and trans have been rebuilt with better internals and last i checked it was pushing 301hp at the wheels( i plan on getting those numbers up)

    Honestly, it would be much easier.

    Which motor and wiring is the car setup for now? If its already a 302/aod car, then its a bolt in swap with very few changes to drop in or covert to a h.o. motor.

    Check out coolcats.net and do some reading.

    Its not on the road but the motor swap is pretty much done.

    4.6 k member spaced 5/8 down under main rails 1/8 under lower mount. Modded rad support to fit 4.6 coolers. I modded the trans cross member mounts but I believe you can purchase a custom cross member. Custom drive shaft. Computer sent in to eliminate PATS and set up for a return type fuel system. Lots of things to consider, hood clearance, exhaust clearance, custom ac lines etc.

    What a great project bodyman! I would love to see it finished! Also, I have the mechanical ability to do it so I'm not too worried �� I can't wait to read your entire write up

    With the amount of Crown Vic P51 cars out there, that would be a good swap.
