Re: 72/68 blazer 4x4 dream/nightmare

Got a good start there. 4.56 will be perfect on that setup. I have 4.10 and 35s and it works great everywhere but the highway. Sm465 so no od. If you stick with the 700 you should be pretty happy. Did you try adjusting the tv cable of the trans? If not adjusted correct it will not shift correct and burn up the transmission. Maybe that's all it needed. I have the same rollbar as you. Havnt installed it yet so it's nice to see how it'll look on yours.
