I have an 05 dodge 1500 with a 4.7 going to swap to 5.7. Just wander if what I would have to change to accommodate it like fuel pump computer or harnesses. I have a wrecked donor truck for the 5.7
I too have wondered about putting a hemi in a 4.7 but from what i gathered it is extremely a pain. Basically just buy a hemi truck. All wiring literally all wiring in the truck has to be swapped, all modules/computers, cluster, and dash controls.
I considered it after engine problems and it only took a half hour of research to draw a definitive no on the project.
If you are doing it for fun and have more money than most people then do it as a "mod" just to be cool like extreme lifts or extreme lowering. If you are doing it just because the hemi is better then sell your truck and buy a hemi you will be way ahead.
