Jon,
I agree with you. The 3.55 was my max. FYI, staying close to the fort worth stockyards tonight and tomorrow.
Buck,
Figure out your plans for the truck. are you hauling, pleasure rides, running moonshine, or driving in hills? Depending how you answer that will answer the question of how fast and which transmission/rearend. There is a lot of knowledge on here that can guide you. obviously jon is one of those. I can only speak about my truck and what i have screwed up.
Good luck!
Chris
