New to engine work and what will and what won't work here. Not afraid to get dirty and turn a wrench. Ive got an 03 Dodge Ram 1500 with the 3.7 v6 in it, with the 4-speed auto. How hard and expensive is it to do a 5.7 hemi full swap on it? What all do I need as far as computers and such?

It's gonna be a lot of work! Not impossible, but it might be easier to find a roll over hemi Ram and change over the cab, bed, etc. It won't just be all the computers, but I'm guessing, cooling system, transmission and I'm sure there's more. I think if you look around you can find a nice hemi Ram that wouldn't break your bank, and sell your V6. If the V6 runs good, someone will buy it.
