just got an 03 1500 reg cab. what mods to these (4.7 btw) motors respond well to? it had a 3 chamber flowmaster when i purchased it and i put a k&n filter in earlier today. i've been a ford guys for years after modding my 98 gt to all hell. throw your ideas, opinions, personal experiences at me please. can you put hemi heads on a 4.7?

 

superchargers work well...

Trade it in for a Hemi the money you spend on mods plus the truck will put you over the cost of a good Hemi. Good luck though let us know how it goes.
