Exclamation Newb need help with engine swap

Hey guys I have a question.I have a 2002 Ram 1500 with a 4.7l and I was wondering if anyone has done a 4.7 l to a 5.7l hemi engine switch? If so about how much did it cost you for the whole thing I know you will need new wiring kit and motor mounts, and I’m not to what else I will need? I need your guys help on this I really want to do it I want to know what ill need and about how much it cost so I can start to save up. Thanks and I would also like to hear your guy’s stories on your engine swap.

From what I understand you'll need to get an engine and harness out of an 03. The 04 has the 4 plug computer that also controls the transmission. You might look into getting a wrecked donor truck because you will have to replace the whole wiring harness, including the brakes. There's a handy guide out there on another dodge forum.
