Building my first tractor which is a 51 B All Fuel. To the point of rebuilding the engine. Tractor was in good shape and not wore out but I've gone through most everything and now ready for motor. I dont enough to know what I NEED to do to the engine to be able to pull at plow days in GA Red Clay. I've got a JD 44H plow that has been gone through with all new or NOS wear parts. Has 14" NOS moldboards. Plan to use 12.4 tires and rear wheel weights for extra traction. Block has to be bored .045 to clean up. I want the tractor to be reliable and not so extreme where it becomes finicky, hard to start, run or tune. There are many parts and shops out there offering high compression pistons, cam grinds, stroker cranks, etc. but I dont want to grind cases or go powerblock. Cam didn't come out because it looked good but it still can. I have a set of 50 rods to go back in, a completely rebuilt All Fuel carb I could possibly swap for a gas carb of any size with the builder and the AF manifold I've already ceramic coated. I have all the new parts ready for the head but dont mind backing up with different valves, etc of that's what I NEED. I've talked to couple of builders, all with parts and services to sell. Not going to be doing pulls but want it to drag that plow through GA clay with relative ease or am I just wishing? Suggestions on pistons, cam, swapping carb, going to gas manifold, head work and/or a good builder to lead me to the right set up?
