uh, well i mean i could be wrong, but i looked over mine pretty well when i built it. i dont recall one. where might it be stamped? the block itself carries a GM part number of 12551366. now, is that really on the block itself? or is it a casting number? not to my knowedge, so thats as sure as i can be.
