There have been some good comments.
Let me add two things.
One, I find that if I take the mountain curves 5 or 10 mph less than the posted sign that my co pilot is much happier.
Two, keep an eye on your engine temp when climbing long grades. If you think it is starting to rise much above normal, then force the transmission into the next lowest gear. The higher RPM will increase the fan speed and pump more air through the engine, both help with cooling.
Not only more air, but going slower, you will use less HP / minute, meaning the engine will generate less heat.
Not too many vehicles have cooling system design to drive with gas pedal on the floor for long minutes. Some diesels can do it but this is one of the common misconceptions.
