So if I get a complete engine, will it be a direct swap with the trans, wiring harness, etc...?
no. you need ALL that stuff from the donor vehicle to do the swap.
the 4.7s and 5.9s are totally different, and nothing interchanges between the 2, however, since you COULD get a 5.9 Durango in the same years as a 4.7 Durango, then you can get all the stuff you need from a donor truck.
Might even be able to use a Dakota R/T of the same year for the donor parts.
I don't know enough about the transmissions to say for sure, but I know for a fact the engine harness and PCM has got to be changed. 5.9s used distributors, 4.7s use coil packs.

I wouldn't, in fact I would prefer it. The Gen I Dingo with a 4.7L is a nice rig all around. A Gen II with a 4.7L is a different story.
What yrs are gen I vs. gen II?

the 5.2s and 5.9s are known to be good up to 200K miles, some even beyond.
I've had an 05 Durango 4.7 and had no problems at all in the 60K miles I put on it. bought it new and never had a problem. towed with it and it did fine too.
now I have an 04 Dakota with the 4.7, it's got 80K miles on it now, and haven't had any issues with it.
when it blows up, or gets valve train problems like everyone says they do, i'll post it up here, but I have a feeling the problems were only on the earlier 4.7s, (like the one in your ride now) where they had some PCV issues and the top ends would sludge up from water vapor. there was a fix that they did, I think in 03, which fixed the problem.
I've also heard that at some point, something inside the 4.7s changed, a tone ring on the crank or something, so you cannot take a later engine and put it into an earlier vehicle, without opening up the engine, removing the crank and changing the tone ring. I don't know the exact specifics, but I've heard of guys having that problem

In 2002 They changed the engine controler. Also the timing chains and water pumps.
