Just my $0.02. Adding coolent adds viscosity which promptes laminar flow through the cooling sys. versus turbid flow with straight H2O which has limited heat transfer/exchange due to residence time, but too much coolent limits the heat transfer. I mix 60:40 just in case but the car is stored in an environment that will see below 30 degrees but never had a problem with over heating since a radiator recore when purchased in 2012.

Restoring and maintaining old cars and old boats....oh what fun we invent for ourselves. Seems to go in stride with ....You don't live it until you own it....Three steps forward....two steps back ....
