I knew someone who used to drive his 120 across country and he had to overhaul the motor on a regular basis. Let's be realistic, the car has a top speed around 80 mph. My modern car will do 140 but I wouldn't think it could handle sustained cruising at 105 mph. We dyno test cars with the throttle wide open for hours and sometimes they blow up.

Floyd Clymer ran the splash oiled Chevy at full throttle for hours, but that was a new car. One reason I think the 320 engine is better all around than the 384 is because it has less crankshaft flex.

Beat on those old motors and they will blow up.
