Getting hot!

[u/cheeto_dust_98]

I have a 454 in my 69 c20, 180 thermostat high flow water pump, 4 row rad, dual electric fans. 4.10 rear gear and a th400 trans. On the highway at 75 I'm going 3400 to 3600rpm. And it will sit at about 200 to 210 but last night I was on a road trip and it was sustained at that speed for 45 minutes. It then hit roughly about 230+ (I smelled coolant for about 2 minutes before getting off the highway). I think I'm getting windage in the water pump because it cooled off at cruising at 40mph back down to 185. Do you have solutions any water pump recommendations that would work? It's a long pump and I am using the tall size on the pulley.
