Hal,

That's good information... I have a digtal water and oil temp gauge as well so I can track the temps on both the dash temp gauge and the digital gauge. I know people have said that the LS motor likes heat. Sometimes I think I get hotter than the car just worrying about temps.

I probably have done just about everything to reduce high water temps in high ambeients. I have 1-1/2" aluminum water piping from my manifold to the radiators, a large 3rd radiator, 190 degree thermostat, new aluminum radiators that replaced the factory radiators.

I've driven the car cross country in temps over a 100 without it boiling, probably the biggest worry is watching the oil temps in stop and go traffic over 90 degree ambients. I've never been over 250 degrees on the oil for long. I have a small oil radiator which has helped that.

Proof: last trip to California I had to stop on a border inspection on Highway 8 going into San Diego, the line was over a mile long, the ambient was 104 degrees... that's no fun. I said to myself if they would put the same effort at the border it might do more good...

Thanks again for sharing your knowldege with us...
