Here are the photos:

Photo #1:

+100°F day 75 mph with 7 blade fan and AC-Delco Severe Duty Clutch

(I also tried a Hayden Severe Duty Fan Clutch and it also kept temps up around 200°F all the time.)

Photo #2:

+100°F day 75 mph with 7 blade Lincoln flex fan

(The car will not ever get any hotter than this, even in traffic, verified by mechanical guage and ray gun.)

With adequate cooling sytem capacity, a good operating temp is one that is within a few degrees of the thermostat rating...

Not to rain on your parade, but that's no big deal because you're not running a/c. I run a non thermal clutch in my 72 Formula with a/c. Without the air on, the car will run 170. With the air on and in traffic, it'll get to 210.
