Although most Loadstars were set up with a governor to limit the rpms, it is quite possible to run without one. But you must have a decent driver who is not trying to over rev the engine. The governor was put on to basically protect the engine from inexperienced and idiot drivers. The same engine was used in the PUs and Travelalls without any governor, and they had a long life. The 345 has good tolerance for higher RPMs, while the longer stroke 392 has less tolerance.
I just checked my 1963 IH service manual. The 345 is rated at max Hp at 4000 RPM, and max torque at 2300 RPM. It states the governor limits the speed to 3800 RPM. The governor on a truck has the function of limiting the RPMs, quite different from the function of a governor on a tractor which controls engine power to hopefully achieve a constant RPM.
If the governor fails on our Fleetstar 10 wheel grain truck, it will be gone. I can drive with the tach. Our '64 Loadstar (304 engine) lost its governor decades ago and the truck runs fine without it.

The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
