'66 Valiant Running Hotter than Expected

Geeze guys I will get to it when I have time. I spent some time today testing the gauge against a thermometer before I had meet someone who I was going to look at a Signet Convertible. This is not a super high priority right now. The gauge is close. At 180 the needle is about 1/3 into the normal range. Talking to my buddy his 66 Plymouth is almost exactly the same and when it is kissing the upper line line of the normal range it is at 220 (he mapped it out). So it was probably running in the 210 range at the red light within a couple minutes of stop and go after getting off the freeway. This is with the AC off and at a chilly 95F ambient.
