Cracked block- how serious is it?

I was cleaning up my block today in preps for paint, and found this crack. Also the middle freeze plug appears to be twisted. The car didn't appear to leak coolant, but I've only had it running for about thirty minutes before I took it apart. The car did heat up a little, but I had not diagnosed it prior to embarking on the frame restoration.

A little clarification- the pictures are on the drivers side of the block, between #5 and #6 cylinders. 1937 115c.

How serious is this? Should I be looking for a new motor?
