Yes, absolutely.

do you know if I would have to change out the ecm and the wiring harness?

I don't think you'll have any problem with using the existing wiring harness but the PCM should be reprogrammed for the correct VIN if you swap it, but you might be able to retain your old one. Everything should bolt right into place. Dodgetalk.com and Ramforum.com have dedicated threads to engine swaps for Dodge trucks. I don't see anything that would keep you from bolting the new engine right into place.

thank you
