No such thing as a 'small block', or 'big block' when you're talking about Poncho engines. You might think of these behemouths as large journal engines, but the block is the same size on the outside.
Pontiac blocks are the same size externally. This is no big block or small block Pontiac engine. The smaller the displacement the more water/antifreeze the block holds. The 265/301 and RA V 303 engines are short deck blocks but are still not "small blocks"
