This is at 8600-feet at Cloudcroft,NM where baro pressure is reduced.If I run the heater fan,the problem goes away.
This used to happen to me close to sea-level in my El Camino with the 396 c.i. big-block,say,waiting in line at a drive-in theater in Van Nuys,Calif.This is probably where I used the trick for the 1st time.I'd blame my girlfriend.

I know that road, its pretty hard on the cooling system. Used the heater many times during the summer to keep the engine from getting too hot. But I usually only need to just keep the rpm up to move more water.
One thing you might consider is seeing if you can find a high flow water pump, they are supposed to help even when the engine rpm is lower.
