Engine with no anti freeze only water and water wetter outside in 32deg weather for overnight. what do you think?

I wouldn't risk it, a couple of bottles of 50/50 antifreeze are a lot cheaper than a new motor

I guess your right the hourly only shows a low of 32 from 11pm till 6am if it even gets that low. I was just going to load up on the trailer tonight instead of the morning

Lay an incandescent drop light under the hood on top the motor, near a water passage. Enough heat will transfer from the bulb to keep it from freezing at 32.

I never thought of that wow

Would it be convenient for you to drain the block?

I have to be at track at 830 so if I load tonight would be easier

You would be surprised how warm it will stay with a 100 watt light bulb under the motor and a blanket or tarp over the top to hold the heat in.

All tucked in blankey up top and a 60watt heat lamp.

FWIW, I had my car sitting on my driveway overnite with nothing but water and a bottle of redline water wetter in it and that night went down to between -5 and -10*C and early the next morning I checked it and the water hadn't even come close to starting to ice over on the top.

Thanks all I ck it late last night the motor was kinda warm. I put a glass of water outside and it never even got slushy.
