"I've read of 50's vintage AD trucks going well over 200K miles."
I am not following the banter/bragging, but does someone know of a 216 or a low-pressure 235 going 200K without a rebuild (or, at least a valve job)? I'll bet my 1954 A-D high-pressure 235s were lucky to go 50K miles before lower-end rebuild?
Or, is that 200K road miles on the truck, not on the original engine? Kingpins, rear axle seals, etc, etc . . ?
