Pulled up a 16 just to “keep it real”.... I can’t swing new, ever! . This is what I saw that would make me “consider” a 6.4. Reality is that I’ll probably keep using my 01 until I flush my racing hobby. I’ll agree with Chip that my 01 in stock form was a bit of a letdown. Also made me realize why so many had tuners on them when they came in the shop. I’ve had a edge ez, rv injectors, and a trans I built with goerend parts since 38k back in 04. Got a buck 80k on it now. Last year a decent 11 came in on trade. I was star struck and brought it home and hooked the trailer to it and proceeded directly to the gawd awful grades heading out of this hole I live in. I’m not sure if I was more disappointed by the 6 speeds and 3.7 gear, or impressed with the minor tunes and my 3.5 gear in my 01. My junk just plain out towed it. Looking back I’m glad I skipped on it. The 14 newer is a much better pickup.
