Correct 340 Engine?

You guys always seem to respond quickly to posts so I've got another.

I've got a 1971 Demon 340 project that has the #'s matching engine (according to the vin stamping on the block)

What's screwy is the casting on the block is 1969?
I would have expected a 1970 block - is this highly unusual or common to have such a block hanging around for that long?

Just curious..
