I did a search but could not find much on a 4th gen ram. Is it possible to swap a 4.7 to a 5.7? If so what all would need to go with the swap amd can the ecu be matched with the 5.7?

thanks

 

It's not plug and play with your 4.7 PCM. It would be best go get a wrecked 5.7 donor truck, so you can get all the mounts, wiring, and PCM from it.

It's a bit more complicated that just dropping the 5.7 in and plugging it into your current truck. You need all the associated wiring harnesses and PCM to support the 5.7, motor mounts, radiator, etc.
