Thats a nice truck you have there! Also a great idea for growing hops too, we used to grow our own hops for home brewing.
The engine code has me puzzled- do you have better pictures of the entire engine? XTO suffix code doesn't seem to exist in any of the books (including The Lime Book) or on websites. The S is Saginaw engine factory and 0304 is March 4th. But the XTO is throwing me and it almost looks like XTC but even that one doesn't exist. There is a TC suffix but that is a 348 big block (which would be appropriate for 1963) and it doesn't resemble a 327. XTD is a service replacement engine 283 for 1965, 66 and 67 but would be tough to read that as a 'D'
