It was already done before I bought my '52. It came to me with a 67 Camaro rear axle that has 3.55:1 gears. The previous owner also had 5 lug disk brakes put on the front. Cruising at 60-65 is easy and I had it to 75 once with a tailwind.
The rear brakes are no better than the 52 brakes.
'57 GMC 102, Original 347 V8, HydraMatic, 3.08 rear gear, added A/C, disk front brakes, HEI, AFB carb, '98 Honda Black Currant paint. T-boned and totaled 10/12
'52 GMC 152 Stake Bed, Original 228, SM420, added A/C, HEI, disk front brakes, '67 Chev 3.55 rear gear. Gets used as a real truck.
