Hole in block?

LOL reading down and looking at the pics I was thinking I would not sell crap to these guys that are calling a stock casting junk and saying take it back. I am glad someone else with experience posted before me. At least the OP was smart enough to ask us.
Now I feel stupid. I googled first too and nothing. I figured someone else would have stripped their first MOPAR big block down and had a WTF moment too.
