For the best engine life use a ~195°F thermostat. The minimum stat to use would be 180°F. I like to use Cooper-RobertShaw brand thermostats. Use a 3 or 4 row core radiator in a stock configuration with a stock fan shroud and a thermostatic clutch mechanical fan for maximum airflow. If you need more cooling than that use an auxiliary pusher fan on the front side.
