so as we've addressed my 190k mile 3.9 has some issues, excess pressure, ticking heads (louder each week), and well its got almost 200k miles for god's sake.

so the debate is this; tear down and rebuild the whole bloody thing; or now i've got a fella i do work for offering me a 4.6 low mile disco engine for next to nothin (maybe a grand). I know swaps have been beat to death on the forum but I can't seem to find straight answers to what is involved.

so does anyone know what all i'd have to swap with the engine to make it work? tranny? ECU? wiring? i'm assuming power steering, a/c, alternator would all have to go? anyone know if the mounts match up?

help? i'm moving from colorado to NJ this fall so if I'm gonna swap i may need to get on it. otherwise I may try to find a shop near NJ that will do the rebuild for me. not much in southern colorado that I trust.
