Pontiac blocks are all the same dimensionally 326-455 but internals differ.
You could put 400 pistons in a 350 but will more than likely need to be sleeved. I would start w/ a 400 block. I have a pair if you are interested. Shipping over the boarder would be costly though.

Takid455, I might be interested in a 400 block to build a motor for my 69 Firebird. Can you PM me with info about the blocks you have and how much your asking?
