Default thermostat suggestion

I just got finished having my 306 built. Runs real strong, but the temp gauge (brand new Auto Meter) reads about 160-170. I'm thinking this is causing me to be rich since the computer enriches the fuel mixture until the motor is up to operating temps. And that normally is at 180-190, right?

I'm thinking I have a partially stuck open thermostat, so if I replace it, should I go back with a 190 or 180?

Thanks for the input!

Car will run warmer...cooler is better, I like the 180* helps with detonation and keeps the car cooler for summer. Don't know why anyone would like to run a 195*

Go with the 180 because thats where the eec goes into closed loop and once it gets to that temp its going to atleast stay that temp.

A 180 will work fine. If you have your car properly timed and a cooling system rated for your power you are good to go.

I wouldn't run a stat that low, you car wont ever get out of closed loop and you will run rich, 180 should be the lowest in these injected 5.0
