What are the ideal gears for 10bolt/700r4/33\'s??? Any thoughts? I have a stock 10bolt rear, blazer is a 1985 that came with a 305 orginally. My transmission guys says a better guy might take some stress off of the 700r4. Im on the highway 85% of the time these days. The truck has 3.73's now by the way. Also, do i have to have the same exact gear ratio in the front as I do the back? I have been told that it would be ok as long as I am on slippery ground when in 4wd...nto sure if this makes sense so thought id ask here..
