Frozen block

I did the same thing a couple of years ago. Maybe I go lucky, never had a problem with a crack. What I did have a problem with was I did not change out the frost plugs and lost 2 of them the first time I had the motor up to temp.

Replace the frost plugs. Pressure test it, if it holds I think you'd be good.

About the draining the rad and adding anti freeze. I rented out my garage to some buddies to store their race cars 1 year and during a real cold snap 1 of the guys showed up just to check the rad/water. He drained the rad, added antifreeze ran the pump to mix it up and the freezing temp of the coolant did not go below freezing... It baffled us for a bit.

We fired the car up, got it up to temp and then retested the coolant and then it regestered below zero. I think that the anti freeze and water need heat to mix properly.
