I just got an email back from GS motorsports, and in addition to Dougs headers, a couple exhausts, a few air intakes, they are working on a Paxton kit for the 2004+ Durango. Hmmm...335hp 370lb-ft stock, plus say at least 50% gain from S/C =502.5HP and 555lb-ft. Now that's a viper truck. :mullet: :jawdrop:
