Block casting #'s are on the drivers side rear of the block.
Yes you'll need to remove the alt to see the pad
(part of the block) just in front and below the pass side head.
The #'s are stamped into the pad and are more of a VIN derivative to further narrow down what this engine is out of.
Too bad Mortec is not working as it was a great site for this info.
