David, I'm in NC and experience some of the same possible overheating issues in slow idling traffic..
I used the 19" Pontiac 7 blade Hayden heavy duty clutch fan, 160 fail safe thermostat, and I removed the ( reduced flow)6" underdrive aftermarket crank pulley and replaced it with the original ( high flow)8" crank pulley .Now 172- 183 slow traffic idling). Pontiac 470 10.4 compression, solid roller engine.
