Scooter, my `88 Iroc runs at 200 max in traffic when the temps are 90+ outside. I use a Jet part # 60600 fan switch, 200 degrees on, 185 off, a Stewart part # EMP-301 180 degree thermostat with 3 3/16ths bypass holes, 30% anti-freeze, 70% distilled water, 1 bottle Red Line water wetter and the parts that made the most difference in cooler temps was installing a 4th gen dual fan shroud and fans. I got the shroud from Hawks, the fans and everything else from Summit or Pep Boys. The fan shroud is the key.
