I have a 2004 mercury mountaineer with a 4.6L V8 that is about to throw a rod after oil pump apperently quit. Anyways, I have found a 4.6L V8 from a 2004 F150. Will it work? I figure I'll have to change a few things, I just want to make sure that the Intake and Exhaust Manifolds and stuff will interchange correctly without a hassel.
