Thanks Mitch. I'll double check the engine code when I pick the truck up, hopefully later in the week. The model on the chassis tag is listed as 1922 /45. I entered the chassis number into WIS, and it showed two engine options: 421.905 and 481.902 (WIS also shows the truck as a 1922 K) 19 it the tonnage, 22 is for 220 hp, I haven't figured out the significance of "K". I haven't found a reference that tells me which OM number corresponds with the listings in WIS.
I appreciate the offer on the torque settings. I may have some questions for you at some point. Aside from a little oil around the valve covers, the truck is pretty clean- not counting the condition of the cab
. I'll keep my fingers crossed that I don't have to bother you too much for information.
