I'll have to look into that. I'm not too good mechanicly but a buddy of mine is and my dad thought it would be a fun little project. I always wished I had bought the truck with a Hemi...do a search on yellowkota, he did a swap in a Dak..I believe it requires the hemi wiring harness and ecu as well...maybe even the tranny. what tranny do you have? my brother in law is going to do the same thing in his 5.9 Dak too..
But hey, I can't stop ya if you want a Hemi. Stay the course and go get a piece of the legend.With the jetting dialed in, the power pulls confirmed that this parts selection put major firepower in the basic Magnum package, with 448 hp recorded at 5,800 rpm and 435 lb-ft of torque coming to bear at 4,900 rpm. The cam, heads, intake, and valvetrain package was worth a staggering 129 hp on the stock Magnum mill. For us, that is a righteous gain for a well-selected assortment of out-of-the-box aftermarket parts on a stock production engine. Far from a raucous and unruly combination, the modified engine idled easily at 850 rpm with 12 in-Hg of manifold vacuum, a level that is right at home in a street-driven machine. With output like this ready for the taking, it might be worth considering giving Magnum power a home in your Mopar machine. --Mopar Muscle
