Thermostat or no thermostat?

I run a 195 F thermostat in my three 60's cars. If you use lower, don't fuss about bad gas mileage. Removing the thermostat will not make it run hotter, but it may run too cool. If you don't care about temperature control, might as well get an air-cooled engine, but VW's needed rebuilding every 80K miles.
