I’ve never tired to fix somethnig that large. Some off the wall ideas are to rig up a jig using a large jack ( several tons) and use the jack to sqeeze the crack shut. Or maybe something with hand winch so you have more leverage that the handles on the pipe clamps. Another would be to cut the block on both sides of the at the crack and then glue the rest back together.

How many people does it take to pick the thing up?
