My truck has a 4.7L in it. The motor is bad and I want to swap the 4.7L for the 5.7L. What do I need to make this happen?

Basically everything needs changed. That is why we always recommend direct fit replacement parts. Motor mounts, wiring harness, vacumm hoses, computer, all sensors... I'm not even sure the trans bolt pattern is the same.

Anything is possible, but in my mind, it isn't worth the effort.
