You're right Ron. Given identical atmospheric conditions, you will run
quicker/faster at the lower elevation.
NHRA has altitude correction factors for tracks above 1200 feet elevation.
You may find that Keystone is listed as being at 1210 feet. I've been told
NHRA has some method of determining elevation for it's tracks that may be
somewhat different than the actual elevation. I'm not sure how they do it.
Anyway, here's a link with some good information.

I race at National Trail Raceway, 911 feet, and Indianapolis Raceway Park,
850 feet, and see no difference in performance.
However, friends of mine who race in Orlando, 66 feet, and here at the Mopar
Nats are about a tenth slower at National Trail in similar weather.
