i'd do a flywheel & clutch combo while the tranny is off, and the timing belt & water pump. I'd also baby it for a good tank of 2 of gas... Don't know how long that motor has been sitting around. Did they have the 4.7 final drive in the 97 ITR's? I'm thinking it's 98+ years they got that.

Either way. Great swap to go with. If you got some extra $ and some more patience I'd do some nice engine mods while it's out, hell if I ever do another swap again I'm putting all new bearings and seals and rings in. I don't trust any swaps these days.
