I was kinda leaning that way. The only reason I was thinking of stepping upto the 4.10's besides the fact i could do the locker and gear for $200 is when I use overdrive at 50-55 mph the rpm drops to about 1500 which is just below my cams powerband that starts at 1600. So acceleration and maintaing speed in overdrive below 60 takes alot of throttle. Because of this I have learned not to use overdrive untill speeds of 60 or more. I was thinking that the few hundred rpm increase of the 4.10 might help that but its not a neccessary endeavor.
