Re: 302 overheating
I am relying on the factory gauge, but the engine is ticking like it's hot. It's not boiling over, although it was overflowing out the spout on the overflow until I replaced the (brand new) thermostat with a brand new thermostat. The newest t-stat made the overflow stop boiling (as if there was still air in the system), but did not quite correct the problem.
Before the t-stat replacement it was running cool at idle in park, but would overheat while moving (which is very backwards). I could get it to cool down on the move by putting it in neutral and revving up the engine or accelerating in gear.
And the fan is installed correctly (one of the threads I found said that people sometimes install it backwards).
