I'll agree with that ^^^^ to a certain extent as in, my 3.7 is plenty enough for what I need and how I use my truck. I do think, though, no matter what engine one has in their Ram, HEMI or not, most folks will do what they can to squeeze as much out of it as they can be it mods for fuel mileage or mods for performance. My motor is stock and I intend to keep it that way. I bought my last truck for a project and this one to enjoy lol. Had to play devil's advocate but won't be long before the 5.7 owners are going to be jumping on the 6.4 HEMI! It's kind of like a dog on a leash, the leash is ALWAYS 1 inch too short!
