Temps should be under 200*. Check for something blocking the radiator. You did not have problem when you drove it last. Or coolant leak.

Check for radiator blockage, check for fan operation (common failure) and check coolant level/condition. Vettes pretty much need the radiator area cleaned/cleared out every 1-2 years. Stuff loves to build up and block all the airflow.

just picked it up in arlington virginia drove all open expressway home // with some town traffic 175 miles no issues ran fine temp around 200

In traffic 200-220 is normal. Mine usually fluctuates between 214-218 in heavy traffic.

I wouldn't worry about melting the engine. Mine's run that hot for 11 years and 135K miles.

I've read thousands of posts over the years from members whose cars run as hot as mine and almost as many posts who insist it's abnormal. There seems to be a large variability in running temperature and I'm not sure exactly what accounts for it.

Car will flag a warning around 250f when it is too hot.
