So I'm going to swap out. I bought my 2000 3.9 QC 2wd, and am going to swap for a 5.2 from a 2000 durango. I am getting the engine, trans, basically everything but the wiring harness (its fucked up), alternator bracket (sold) and power steering pump (sold). Would I be able to use these things from my 3.9? Would I need to re-yolk the driveshaft? or is the 42re and 44re the same? Basically I want to know what I need to make this work out. Do I need the radiator? I havent done an engine swap before but Iv got a friend helping me do it. I just want to make sure I get all the parts I need from the donor vehicle, and whatever extra I might need to get it all done as easily as possible. I was going for a hemi swap in this truck, but I came across a good deal and that much fab is out of my skill range, for now. Any info on exhaust? Any info on anything at all? Tips, suggestions, its all welcome.
