I have a 92 350 dually 2 wd with the 7.3. It has a aod transmission in it and all and all the truck is great. But, under a load she drags and even the little hills kill it. Now its not my daily driver and only gets used a couple days a month. I was wondering if I got a c6 for it, would that be the easy fix Im looking for for that extra pep merging onto the highway or should look around for a lower geared rear and keep the trans the way it is. For as much as I use it, fuel Isnt my biggest concern, merging onto 95 with 4 horses on my back is. Am I thinking right or should go another route? I
