64 barracuda runs hot

Keep the fan close to the radiator. What kind of fan is it? How do you know the engine is running hot? Have you put a known good thermometer on it? Just seeing the temp gauge go up a bit is normal. Any coolers in front of the radiator? I assume something has been modified up front if you have a 22" radiator as they only came with 19's that year. Is the core support sealed to the radiator on all sides so the air can only come through the radiator and not around the edges?
