2008 4.7?

Ok so the 08' 4.7 has 305 hp. Plain nd simple, how do i get that in my truck? Is it a part swap or complete engine?

Any help is appreciated

From previous posts, a '01 WJ....

If your goal is just to have a 305 hp 4.7, it's as simple as Y-back exhaust, intake, TB, tune, and either the cams or intake manifold of your choice.

I made ~305 hp on 4" intake, 3" catless exhaust, 71mm ported TB, 08 manifold with adapters ported by me, and a tune.

Re: 2008 4.7?

the 305 hp 08+ 4.7 is very different from a gen 1 modded to 305 IMO

Realistically. ~1500,, MAYBE 1000-1200 if you get creative/find good deals/do the installs yourself (minus the welding on the exhaust).

Depends on how dialed in the tune is. My tune was not all that great (needed more refinement) but even with a lift and off-road tires it pulled significantly harder from 3k-6k. Sounded great too.

The 4.7 is very similiar in design to the PI 4.6 motors, only a little more detuned in certain aspects, and with slightly better heads (not saying much). The lashcaps for reground cams, valvesprings, etc are interchangeable.
