No, "Cosworth" blocks are merely selected Pinto blocks for there tighter bore tolerances.

By the dizzy there will be four numbers which relate to each bore, Cosworth asked for only grade 2 and 3 bores to be delivered to them i.e. 2222, (This is irrelevant anyway once/if the block is rebored) that and YBxxxxx (Unique number) cast into the front of the block above the water pump are the only differences.

YB is merely based on a Pinto.
