Default 3.9 to 4.7 engine swap

I have a 2001 3.9 dakota and i want to swap the engine for a 4.7 v8. Will that engine fit in and if so what would have to be adjusted for it to fit. I would really appreciate some help!

The computer, engine harness, engine, and transmission from a 4.7 truck. It's a huge overhaul. Technically the gauge cluster is also different, but I think 2001 you can get away with a mix-match.
