So I have a 2006 1500 with a 4.7L. This truck has been great to me had it for years, love it, don't plan on replacing it anytime soon. However the 4.7 is starting to get tired and I am starting to look at my options. I do have a few choices for low mileage 4.7s in my area, but I am wondering what exactly it would take to swap in a hemi instead. I do know that because I am a 2006 The truck has CAN bus and I assume I will probably need to get a hemi with the MDS system. From What I have been searching not many threads have been made of people doing this swap on a truck of my year or newer. What exactly would I need to get, or would I be better off just sticking with my 4.7
