3.7 Ram
Guys, I believe that with the 3.92, our 3.7's are about as good as they are ever going to perform. Yes, you could spend all kinds of money and effort to hop them up, but why bother ? If lots of power is what you want, you've made one mistake already. Just trade it for a v8 new or used,....I'd doubt any enhancements you could make to the 3.7 (other than the 3.92) will suffice your appetite, and then still not likely. Do like me, be satisfied with what you have....a darn nice truck that will haul whatever you need to, a comfortable ride, reliable transportation, great looks. If your towing needs are modest and short haul, you won't have any trouble. Shifting in and out of the gear set, well set your cruise and relax, enjoy some music or a delightful companion. I seldom travel interstates for long distances, but when I do, the 3.7 is more than adequate and I'm always in the left passing lane. I've only "floored it" one time just to see what it has. Regardless of the "almighty hemi only" dribble and hype on this site, make your own decision based on logic and your true needs. Forget the mods, trade if you can't stand it, or enjoy and love what you have. Ummm,...guess that could be said in a lot of things about life in general.
Be happy, love and enjoy what you have in life, be grateful for your talents and good fortune, and I wish all of you a great and prosperous 2015.
