Re: 1960
About 2300 rpm with 235-85-16 tires. Rear has the stock 4.10. This truck was a 4 speed truck originally. Hydramatic trucks come with higher gears from the factory. These autos are deep geared because they don't have a torque converter. It's very responsive for an old auto rig. It really goes through the gears fast its in 4 th by 30 in direct. I have considered 3.54 gears with the od but I don't really plan on much over the road driving with this truck. I have a couple of these and am considering putting one in the 65. It's a 4 speed rig that already has 3.54 gears. I also have a little Watson 39 that is a little 3 speed it's a little smaller than a 420 Muncie it has 50 percent under , direct, and 21 percent over. This will probably end up in a 4x4 between the trans/transfer case. Here are some old od boxes the long one is for a ford model t and the little one is for an old jeep
