From my old petrol head days in a big way where cruising at 150+ kms for near 100 miles the temp would rise to about 200, but slowing down to 100 - 120 would cause the guage to drop back to normal on a HT monaro guage setup very quickly.
What "normal" temp is may be more the question, the commodores do run fairly hot under the bonnet out in the scrub where outside temps are well over 40 deg C.
One trip to Melbourne the back way caused big dramas when it was pushed hard it would run sick, for no visible reason, the problem eventually found was that the fuel was literally boiling in the tank "it could be heard" so the carbies were getting bubbles instead of pure liquid fuel.
Racers will know what a cool can is, those that don't, it's a glorified can with the fuel line made of metal is coiled around unside the can which is then filled with dry ice or a ice / salt brine mix well below zero deg C depending on the length of the race.
It does work very well BTW, another trick is water injection, where depending on what the throttle position is and vacum etc water is squirted into the carby bores along with the fuel, the water increases compression and thus HP.
