I think you need to figure out where else this engine is being used and cross reference the parts you need that might help.

It was used in the Durango's for sure and quite likely the Aspen. I was just looking at headers yesterday but found nothing specific. So now I am thinking bigger throttle body, headers and maybe free flow cats. For the size of the displacement, there should be a decent amount of power left in it. I might call a few performance shops to see what they might have done or if they have any other options. If I could eek out 330 HP w similar torque gain I would be a happy guy......

I just searched the net for headers and it looks like were out of luck. It seems like there wasnt enough room in a lot of the engine compartments that the 4.7 L came in.

That is exactly what led me to research a supercharger 07JeepXK. Short of swapping out the cam at a hardcore shop, there seems to be little that can be done from a bolt on application standpoint.
