Two other points concerning the "K4706976" number that you said was on your paperwork.
First, the line in red in above referenced page says "There is no evidence yet
as to whether there was in fact a Master Commercial Series DB "K" prefix "Commercial" motor". My point being that on comfirmation of your inspection, you may indeed have one.
Thanks everybody for your help! So, yes, it is a 207 engine, and it does have the K code stamped before the rest of the number, just behind and a little over the gas pump.
After I found out what engine it was, I ordered a few parts from EGGE, which I got already. Just today I started the engine again, after cleaning carb and a few more things. We adjusted valves and the engine works beautifully, but I haven't moved the truck yet.
Again, thanks everybody for your help!
