68 Barracuda 440 getting hot in traffic

For many years I would get very nervous if my Mopar showed a temp much past 195, but when I got newer cars/vehicles I noticed that most run around 220 degrees, so on my 416 I really paid attention to the temp watching the electrical gauge I have (Speedhut) in the cluster and using a hand held IR thermometer. I discovered that gauge is not super accurate. I then tested out my 52 B3B (w/56 Desoto 330 Hemi) and discovered that the gauge in that as well as the EFI hand held were different than the handheld (mechanical gauge is quite a bi off). In other words, I discovered that unless the temps are getting to 220+ I am not overly too concerned. 200 - 215 wouldn't scare me too much.
