Quick question on coolant/freezing

[FMJ]

I filled my 440 with water to run it for the first time becuase i knew it would spill all over and i didn't want to have to deal with anti-freeze. SO anyway it's going to get down to 32 tonight, and even though i took the plugs out of both sides im still worriued that somthing might happen? I've been having some bad luck with this thing and i really don't need to lose it all because of this. Should I add anti-freeze, or will it be ok?

You should be ok but just leave the radiator cap off.

you could blow some air around in there and you might get some water out. i think youll be fine though.

dont forget the heater core needs draining. and if pulled block drains it should be o.k.

Just minimize the amount of water in it and leave all the available ports and plugs open. The water freezing isn't what kills you, it's the fact that it expands in the process. If you get most of the water out you should be fine.
