My 2007 Ram has 338,000 miles and will surely not last forever. I am considering two options as far as a replacement: Either swap in a lower mile 5.7 or rebuild another and swap it in.
I'm curious as to which years are direct interchange. I also wonder if there is anything different that has to be done upon a fresh start.
I've done numerous engine swaps with old cars but only a few fuel injected later models. Once all the components are installed and hooked up, is there anything required to do besides turn the key and go? Does the computer need any "reflash" service or will it simply work as before?
