In theory its not too hard, since you have both vehicles already. Just swap everything from the Hemi to the 4.7. Just got to remember to do all of the little things like motor mounts (not sure if Hemi mounts match 4.7, but I doubt it), computer, etc.

When you remove the 5.7 from your truck be very careful not to damage any wires or plug from your harnesses as you will need to swap them over to the new truck body.
As USAF2006 mentionned you may need to swap the engine mounts as well.
Good luck on the project and keep the forum informed of your progress.

In addition to the motor mounts, check the transmission mount and cross member.
You'll want to swap the 5.7L PCM, harness, sensors, radiator, coolant tank, power accessories, etc... as well.

thanks everyone i think before i do the swap i mite do some work to the motor what can i do to the 5.7 motor that will give it more power and let it breath better but still be reliable .......i love the 5.7 but it would be nice to let those horses run
