Re: Storing a project car in cold weather.

I've found it better to store cars with antifreeze than drain them.  Lack of 
a total system fill leads to rusting of the waterpump seal causing a leak 
later.   The block tends to grow rusty fuzz that turns to silt next time the 
engine is run. 

If you were to ensure all liquid was out of the motor and the internals dried 
out this would not be a problem but doing that on a installed motor is 
difficult.
