The air gets a little thin up in the mountains. A carb will run rich unless it was tuned for that altitude. I'll never go to the mountains without fuel injection again. Back in 72, I top ended at 45 mph on interstate from Denver to Springs in a 68 1/2 Econoline with a 240. I live at an elevation of around 750 ft. When I took drove up to the tree line in the Rockies, I often didn't have enough power in 2nd gear and had to downshift to 1st. I must have made all the people stuck behind me real happy.
Ok I give up...

Heck, just skip second gear and be done with it. 
Wind 'er tight enough in first and you'll hardly miss it! 
My brother tore second gear out of his new Maverick in '70 or '71 and was afraid to tell Dad. He drove it that way for weeks!

how about lifters adjusted too tight?
Hey Blueroo....
I'm really reaching here,but it almost sounds like it may be going rich at higher speeds. The fact that it's worse cold means that the choke may be involved so......... adjust or baling wire the choke linkage so it's wide open. That will take the choke out of the equation. Then give it a try with fingers crossed.

I've had similar problems with fuel filters that were partially clogged. There is additional demand when going uphill. There's less demand when going down. This led me to suggest way ago to check the fuel pickup strainer/sock. Blow the filter in reverse, and see if any gunk comes out. In addition, blow out the whole set of lines right up to the carb.
One issue with heat on our cars, is that the muffler sits too darn close to the sending unit/pickup. This adds heat to the tank, warms up the fuel, and can cause deterioration of the rubber hose that connects the tank to the hard line.
