With a carburetted engine, there is no ECM that controls things, so it's not possible to deceive it into richening the mixture, however, cold still equals rich, unburned fuel, which equals thinned oil and washed down cylinder walls. If you're racing only, who cares, but if you're talking about a daily driver, then it should be a concern. A 180 t-stat in a carb'd engine is perfect. Any colder, and you risk the fuel not atomizing enough, which will eventually lead to damage. In an EFI engine, the factory t-stat is the best way to go, depending on mods, and it's usually between 190 and 195 degrees.
Take care,
