Overheated tonight: Related to prior issue?

Well the engine finally overheated tonight 250-260 and boiling. :banghead:

I guess I'm ranting because I think I've done everything I can think of to fix hot issue.

I took a 300 mile trip last week and the engine ran 205 and gets to 220 if I push to 75mph. 2.76 gears. Slow down to 65mph and it drops to under 200 degrees. I'm afraid to even use the AC at this point.

This car has wanted to run hot since I've owned it. "Seems OK" around town 180-200.

Setup:72 Swinger rebuilt 318 flat tops .030 over and XE256 factory AC. Timing 14 idle and 34 max and running vacuum. Kinda new (5K miles) 6 blade water pump and 2 core brass/copper radiator with on it. Mr Gasket high flow 180 TS. New fan clutch with 7 blade fan. Lower hose has spring. Factory shroud and hood seals. Ive adjusted the carb a few different times. New gauges.

I changed the TS 3-4 times to a 180 and 195, used water wetter and tried another radiator prior to tonight's issue.

I think the TS stuck tonight, I'll check it tomorrow and I'm waiting on my 3 core Champion CC526.

I don't know what else to do...I'm stumped again! Any suggestions.
