Well, here is my two cents !

Verify the t-state is good, verify the gauge is good, make sure the fan is working and that the temp. goes up to normal while sitting at intersection lights (180 to 210) and then back to 180-185 while running with no fan on.

The weather will affect the temp. as stated....damp, dry, cold, hot etc. Here in AZ it gets up to 120 degrees on summer days, my cobra FE motor runs 190 with no fan on at speed and crepes up to 200-210 while sitting at idle.

As far as too cool and possible wear...I ran numerous boat engines in cold lake water at 130 to 160 degrees for years..never had a wear problem or engine blow up even when I hammer the darn things.
Relax, just keep it in range and do what ever it take based on the outside temp.
Hopefully you will out live your Cobra!
