Yeah airram is coming out with an intake manifold and supercharger just for 4.7s. The best way to add power is boost. You could get a universal turbo kit. Im thhinking about it but am stilll a little sketchy about not getting a specific fit. If you were gonna do an engine swap, i would do a 6.7 cummins. but thats just me

i like the airram site ive already bought a k&n intake from them along with the powerwire with the engine that i have if i add headers, cams, ported heads and possibly a tune when they come out im looking at around what the 08 4.7 is running or just below what the 5.7 has and i figure that i can get my hands on some 08 4.7 complete heads ill be about the same spot to then add the headers and tune maybe airram will see this and start carrying the performance 08 heads if any one knows what the difference is between the 07 and 08 besides the dual spark plug please post that

I do know that the 2008 cams are different then the 1999-2007 cams.

Dyehard, what kind of performance are you looking to make... do you have a specific trip time/speed or even vehicle your looking to beat?
This would give us an idea what you expect and what you would need to do to make that happen.
As Hank pointed out... again Hank thanks for the plug, Since the 2008 4.7L has improved head flow and the intake manifold has also been improved to flow more a set of our CNC ported heads would bring the 1999-2007 into the future. Of course our heads would out flow the 2008 factory castings but that would be the first step into getting to that level. You do not need to swap to a 2008 head, and I personally think it would be easier to install and you could get better flow with less money with a set of our CNC ported heads.
Also if you did swap them you would have to deal with how to get the dual plug set up to work... perhaps it would work with your current wires... thats un known at this time... It would be cool to see somone try it, but do you have the money to experiment and possibly not have it work?
There are quite a few ways to make more HP then the 2008 4.7L... they just come with more HP... so they have a slight head start. My 2002 Quad Cab 4.7L runs just as fast as a SINGLE CAB HEMI... so you can make yours run hard without swapping in a 2008 4.7L.

airram i like the sound of your ported heads prolly mated with an ho cam i would like to get a tune as well but i havent seen any out there all the posts about that on here say they dont have the tune yet would you recomend a tune or remapped ecu also what kind of power are the heads making and if you know with the ho cam
