I am surprised I missed this thread.
My son has a 1946 2 ton. With the original 235 and the throttle plates
removed from the governor, I rebuilt the carburetor, new plugs, wires,
cap, rotor points condenser, timed to factory spec, he hit 53 on a level
section of the interstate for a brief moment with an empty bed.
He normally drove the truck at 42 - 43 and would stay from 40 to 45
range. He used the truck the first fall for his catering business. Then a
few times a week the following spring from last week of April till the
first or second week in June and the number 6 cylinder dropped a valve.
When I took the head off I found a cylinder toward the front of the engine
had a burnt valve. Not bad hitting 53 mph with a tired old motor.
Anyway my son went with a 1954 235 for 19 more HP and 8 lb torque.
He hit 47 briefly returning from a catering event this past summer.
Though he has not and will not try to see what the 54 engine can do
with the truck unloaded for he does not want to risk damage.
