Hey all I have sked this question to a few cars guys and have had many different answers. The question is in a race application should you have a thermostat or be wide open ??
Mike,I run my Dart without a thermostat.Mike and Wayne at Active advised this.I,m running with a stock 318 rad and you know how my 410 runs cool.I also added a liter of BeCool to water.Good Luck.
