Gentlemen: How do you look when you're hot?

On a 30 degree day, the 318 in my ‘73 Swinger doesn’t even make it to the halfway point at 70 mph. The heat blows hot enough to take skin from the bone through. Over the summer, with a heat index of 106, the a/c running max, and hours long stints of 80 mph or more, my gauge ran close to where yours is in the pic. I don’t always put a lot of faith in electric gauges. For me, it’s just a reference to how my car normally behaves.
