Thanks for the info Mike! I didn’t realize the “C” designation didn’t start until 1960! The “Task Force” is new to me as well, is that a special designation for the larger trucks? I still have a lot to learn on the history side of these trucks.

I appreciate the info on RPMs and speeds. My truck is factory 283 (VIN starts with a “V”), however it is not the original engine. The serial numbers indicate a warranty replacement. I’ll be interested in seeing my MPG once I get it running. Currently replacing the radiator core and working on the brakes.
