Hi, Hopefully I can get some recommendations, or guidance.
Some background information:

The engine temperature is getting too hot.
I live in St. Augustine Fl, and temps are getting into low 90's, & at least around low to mid 80's.

'66 GTO , 428, 4bbl, 4spd, Vintage Air a/c, 3:55 rear. Radiator was replaced about a year ago. Flow-Kooler water pump installed, Hayden fan clutch installed 4/24. Looks to be a new 6 blade fan. Fan is 2" from radiator, and has a complete shroud around it. It has a 180 degree thermostat. No coolant leaks.
Also, is there an upper radiator hose bracket available to support the top hose? The bottom of it is about 2"-2 1/2" above the top of the power steering pump.

The issue is that when driving at 40 mph, the temp will creep up to about 200.
If I stop, within 2-3 minutes, temp will go 220-230. If I drive it 3-4 miles, temp will return to 180-190. All of this is with the a/c running, which is needed here in Florida.

Hopefully I've provided enough information for some advice or suggestions.

Thanks,
Allan
