4.6 liter Ford engine, 38k miles . I bought the f-150 for the engine and misc body parts but found another Expedition so selling engine. Truck was only used as a plow truck and toasted the trans. plenty evidence of young 38k miles. ( exhaust manifolds, vacuum hose connections no wear, no bent fins in rad and condencer, no wear in seat, etc, etc. Has new alt and some extra parts. truck in the way so pulled engine in case I use later, but scrapped body. Engine is from 1998 so normal expected fading aging on aluminum parts.
