I recently bought a 84 k-10 silverado. I believe it is all stock except for the distributor and coil, 4 inch rough country lift, a set of 35x12.50x15 BFG KM2's. It has a 10 bolt front axle and a 12 bolt rear axle, with what I believe to be stock gears.

The gears are way to tall for the tires, ( I don't have a tach but at 65 she is chugging at real low rpms and could almost downshift, so I'm thinking of going to 4.11 or maybe 4.56 gears. I have a 700r4 with o/d, any opinions? This is my daily driver as, well as my play toy.
