Engine Serial Number Help

I bought a 2000 f250 superduty with a 7.3L powerstroke that is allegedly out of a 1997. Can anyone tell me if it is a '97 and anything else you see in the serial number. The number stamped right above the oil filter is 181739C2.

One possible clue - you could remove the freeze plug from the top of the engine block in the valley and peer inside with a light. On the engines that went into OBS trucks, there is a lobe there on the camshaft that drives the mechanical fuel pump. On engines that went into the SDs, there's no lobe there.

Was the TRUCK originally a Powerstroke?

That number looks to me to be the part number from IH, as most parts # from IH end with a C1, C2, ect.
