What do you consider hot? Do you have a temp gauge or heat gun that you use to check the temperature?
1. You may want to try a 185-degree thermostat, as it's a misconception that having a cooler thermostat will make your engine run cooler. Especially with a big block.
2. How long is it running for when it gets "hot"? Even with the fan running, cars aren't meant to sit idling and are meant to have air flowing through the rad from going down the road. Does it run hot when you're driving too, or just when it's idling?
