I see where you are trying to go with this: So if it "had a standard bore" means it was never bored, and if that means it was never rebuilt and they don't last much past 50K and it is the original motor and it lasted til 2011 (meaning the original motor was the one immediately preceding the 56 in 2011).....maybe, I say maybe, the truck has 39K. Why was it replaced? Was the 216 running in 2011?
It may have, by circumstantial evidence, have 39,000 original miles if enough other condition items are present. Now let's forget it.
