Welcome to JustAnswer!!!

If you have the 4.7 then I would suggest getting another 4.7 to go in it's place because if your thinking about upgrading to the HEMI then you will need to change engines, engine wiring harness, PCM, Transmission, etc.. It's much cheaper to go back with the original..

I hope this helps and thank you for the positive rating,
