Just learned today I need to replace my 4.7 motor , so now that I am in this position I would like to go to a bigger, faster motor but don't know how to go about doing that with truck set up with the 4.7 , meaning the easiest with minimum changes and the most economical any suggestions would be greatly appreciated

 

Search hemi swap in this section. Read, read, read.

 

Minimum changes and easiest lol? Put a fresh 4.7 in it's place. Maybe some custom cams and an intake manifold swap.
