I have 1956 Chevy 3100. I have owned since 70’s. I installed 3.38 gears about two years ago after my 3.90 ring and pinion wore out. It was the best money I ever spent on the truck. At 65 mph, it improved mileage about 3 to 4 miles per gallon, plus the cab is so much quieter and the engine seems so much happier to cruise at lower RPMs. The 235 has plenty of torque to launch the truck just fine even with a bed full of firewood or to pull my boat.
