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!!!

Pulled my old car out of the trailer today. It still has my motor and stuff that is going in the new car. Found a popped freeze plug.
Hope it is as simple as popping a new one in. If not, my season ended before it started.

be careful here. "freeze" plugs aren't made for freeze protection. They are present to aid in the manufacturing process. One purpose is to allow the sand to escape after casting, I also think they are used to locate and hold the molds in place during the pour, but I could be wrong about that, I've never worked at a foundry. If you've popped a freeze plug it is very possible you've cracked a head or two and/or cracked the block as well. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/unsure.gif)
