340 Duster running hot

For example.... My car. 11.7 to 1, 340. Original radiator, original fan shroud, Mopar Brand clutch fan. NAPA $30 water pump. 180 thermostat.....

My cooling system is basically stock.... I run the correct Race/Pump mix (if I push it). I run pump gas if I plan to do NOTHING but rumble around town. Timing is where it should be.... Carb fuel mixture correct....


Nothing fancy... Never gets even a little hot.
