Just wanted to share an anecdote about overheating. Several years ago I bought a used 69 Toronado that had chronic overheating problems. It had a relatively new looking thermostat in it and the thermostat passed the boiling water on the stove test. I left the thermostat out and it still overheated. Eventually discovered the butterfly from some previous thermostat had broken off and was stuck in a water passage in the intake manifold. After I fished the butterfly out of the manifold it stopped overheating. Murphy's law strikes again.
