???Coolant Temperature Sending Unit???

My 71 Suburban with a 454 runs right around 190ish almost always while driving. It will hit 220 in bumper To bumper traffic and will creep up to 210 at stoplights but cools down quick once I start moving again.

It may be that this is where 454's normally run? This is only my second BBC...the first was a built 402 out of a '72 truck that I installed in my '65 GTO (when I was 18...and I'm 65 now!) but I never had any cooling issues with that car, even when towing my sand rail with it (in the desert heat!).
