I bought what I think was a 190* thermostat for my 67. My car has a mild 302 roller motor and I went with a hotter than stock thermostat because I had heard the engine will actually run better at higher temperatures. Stock is 160* or 180*? Anyway, what thermostat should I be running? Seems to be the one I have is keeping the engine up past the halfway mark on temperature gauge consistently and it's winter.
