    as im about to rebuild my box, thought it might be a good idea to rack a few brains for some gearing info on the axles, at mo its a stock 88 350 TH700 4x4 running 33s both summer and winter but winter are heavyier tyres due to studs, its a daily drive(low milage though) spend 6 months of year driving on snow/ice hence studed tyres have standard gearing at mo, any one got any hints on what to change gearing to

    4.56 gears will definitely give you more power. I am running 4.56 gears with a 700R4 and 37's and I would say that I am happy with it. With 33's and 4.56's, your blazer should mover like you never thought it could. /forums/images/graemlins/peace.gif

    4.56 , not any lower. i've got this combo and i think its perfect. i get better mileage than i did with 3.73's due to the motor not having to work as hard. i turn about 2600rpm at 75. i get about 10-12mpg. before i got 8-10
