I will look under the hood for the 2nd location of partial vin. on the frame later today.
What I was thrilled about is the 400ci engine. Only has 425 original miles on it.
Again, was/is there such model truck as C1000? If its on internet it has to be right. LOL JK
Another thing my step Dad said was that the rear wheels both spin in the same direction and not like most cars that one spins forward and the other backward. I'm sure it has a name and only known this for classic hot rods.
Second, he's adamant that I use top of the line fuel with a lead fuel additive. Any idea why? Keeping engine nice and coated? Again. Im not an under the hood car guy yet. I know the basics. I'm more of a 2A freedom builder guy. I almost feel I'm not worth such a classic truck. I live close to a small airport and step Dad was also a pilot. He told me if I could to use the fuel they use for small aircraft. Beyond me. He's an old schooler.

C/1000? I dunno. Maybe it's a Canadian thing. Allstate can't wrap their computer system around the C/10 concept either. To them, it's a 'C/1'. As long as its insured I don't care.
BBCs tend to knock on low [87] octane. My 454 loved 91 octane*. AvGas LL 100 is 100 octane with no additives like ethanol, so it's pure hi test. Expensive, as I remember. Engines built for tetraethyl leaded fuel have valves that may get burnt by no-lead fuel. A lot of builders added Stellite valves when rebuilding older heads. If you use the lead substitute, you're OK.
*I had a '67 Suburban K/10 with a PO's added 454 BBC/NP205/TH350/12Bolt 3.73 Rear with Posi-Traction. It would only run well on Premium, except it was OK on Chevron Regular, but only Chevron.
The ''Two wheels spinning'' means it has a limited-slip differential. GM's trade name for that in this vintage was Posi-Traction. "Posi'' for short.
