I run a 700r4 in my truck with a gm 10 bolt and a powertrax valve body locks my converter in OD no electronics also I have the after market valve that lets me keep overdrive through 3/4 throttle.It is well worth it so it doesnt downshift at the slightest touch of the throttle.As far as gear ratios I run 4.56 gears and 31x10.5 tires and am turning 2650rpm at 70 but I pull a trailer so I need the lower gears I would recommend 427 gears with the 32 inch tires and nonlock up converter as trucks are heavy.My 2300 stall converter helps get this 6000lb rig rolling.I run a 500+hp 427 so my trans has the hardened parts inside and I still get 14mpg at 70mph in overdrive and in town it zips along quicker than my buddies 66 Nova with a 350/350 combo. I am quite impressed with the powertrax locker it is quiet,it just goes right in the stock carrier and it is holding up to the punishment of my torque monster 427 big block.
