It's supposed to be 1deg. tonight and wind chills in the -5 to -10 range.

LT1 bird is in non-insulated 3-car garage next to external wall.

Radiator removed in October. Water system flushed by running water from the top of the block (t-stat location) and draining out knock sensor and other drain plug. I then let all the water drain and refilled with straight anti-freeze.

Engine has never been turned over since rad was removed, just refilled, so no water pump action to move the coolant around.

What are the odds of the block freezing/cracking? What can I do to prevent it?

TIA!!!

I've heard that straight anti-freeze will freeze faster than a 50/50 mix. Is that true? Last year, I placed a small electric heater in front of my IT car to keep it from freezing. I only ran it at night when it got below 30 degrees, even though my garage has some insulation. The front of the car was on jackstands, and with the hood closed, just sitting it under the car seemed to keep it warm enough.
