High Flyers

A question for those who travel to high elevations.

I am at about 3600 feet above sea level and am thinking of traveling to nearby Mt. Lemmon at about 9300 feet with my 83 C20 454/granny 4 speed.

I have read a lot about adjusting the carb for the higher elevation, but it seems unnecessary for a short trip.

What will happen if I just leave the carb as is? My concern is that there is no place to pull over on the narrow road to the top and I don't want to get stuck with my heap up there. I have this image of the engine stalling and my truck coasting backward down the mountain.
