Getting hot on the highway with the AC on.

1. It might be annoying to you in the cabin but 200 to even 210 is not a problem for the motor.
2. 410 gears, 3000 rpms, unleaded fuel and a cammed up motor is just asking a lot of that motor on a 90 degree day with a 3 row radiator. Adding volume to your system would definitely bring down temps and likely make you feel more comfortable.
3. The Condenser is hurting your temps on the hwy by blocking most of that 60 mph air flow. If you can get some baffles in there to channel more air into the radiator, that might help.
4. Someone else asked about a shroud. That could be an issue but maybe not for the reason you think. A shroud at speed isn't going to help cool the car down at all. No fan or shroud can pull air through your radiator as fast as hwy speeds. So once you are at speed, the fans and shroud are not doing anything....EXCEPT if it is an electric fan shroud setup it could actually be blocking the air flow from escaping the radiator area and increasing temps.
