One of the stones in the Wall measures more than 40 feet long, and weighs 400 tons. This is the largest stone ever quarried by man - nothing near its size exists in Greece, in the pyramids, or in Manhattan. No crane today can even lift such a stone.
Are all your sources this reliable? Here...
Kockums Crane - Wikipedia
That one could lift 1,500 metric tons.
As for it being the largest stone every quarried by man, well if you go to the quarries at Aswan you can still see a chunk of fully quarried granite weighing approximately 1,000 tons that was abandoned by the quarrymen after discovering a crack. I don't think ancient engineers would have been too impressed by your rock.
Oh, and a perfectly joined piece of dry-joint masonry wouldn't allow a piece of paper in an inch. Your ancient wonder doesn't meet code I'm afraid.
Get better sources. In the meantime you might want to address the topic, which isn't about the size of rocks in Israel, but about how Noah kept all those animals on board his boat with nary a pooper scooper or film crew from Animal Planet.
