I am new to the forum and just started work on a 50 Fargo 1/2T. The question I am asking does anyone if the 51 or newer car transmissions can be fitted to the truck block/bellhousing? A little background might be use-full here. I have done a 51 Mercury 1 ton single wheel pickup restoration, changed out the diff in order to go from a 4.8something ratio to a 3.73. The result was great in that I could cruise at 65, maybe 70. The downside was when the truck saw a hill coming it rested. The gearing was close to peak torque at 60. The other vehicle I have is a 50 Meteor, all stock and with the Borg Warner O.D. This car is really sweet to drive, peak torque at about 60 in O.D. , quiet at cruising speeds and decent on gas. The difference from the truck is the car is not scared of hills and has a reserve gear for passing if kicked down. The Fargo looks like a similar animal to the Mercury truck; unless you change the diff gearing it is pretty much a 50 mph truck as the power is similar to the Mercury. How sweet it would be to add a O.D. trans to this truck and I would suggest the performance would be similar to the 50 Meteor. My trips to local car shows here are from one to about three hours one way, all highway, travelling with a group of 60's muscle cars which seem to have a over-weight throttle pedal problem. I am located in Lloydminster Alberta, and I do have access to a couple of cars which do have the O.D. I seem to be addicted to flatheads. Any help/suggestions/ ideas welcome. Thanks Don T.
