Re: 4.7 performance mods?

two good, easy inexpensive mods are the HO cams and sct tuner. Then throw in a bored/ported tb....

Re: 4.7 performance mods?

I would also look into a 3" exhaust, it is supposed to open up the engine a little more and the right muffler would sound sick. Check out the vendor Kolak here for exhaust.

Re: 4.7 performance mods?

My previous vehicle was a '99 GC with a 4.7 and I didn't go super crazy to get more power. BBK makes a TB that fit like a charm and really increases flow with a K&N set up. A good cat back system is critical. Beyond that I would recommend a "Y" pipe mod to smooth exhaust flow into the main pipe.
If you're really looking to make power, Mopar makes a kit with all the parts to turn a standard 4.7 into an HO. Then again, there's always the supercharger option!
