However my 1965 has the 250. It was a special ordered fleet truck for the Saskatchewan Government and built in Canada so I don't know if this changes things.
I have Leo Santucci's book on modifying the 6-cylinders and it lists that the the 250 was available in trucks from 1962 and my block's casting number is consistent with being a 250.
Any thoughts?

When I pulled it a few years back I remember noticing that the numbers match.

How do I know so much about these trucks?
