For 24 years, I lived in the San Francisco Bay Area (sea level) and visited Las Vegas once or twice a year. I could tell a drop in performance when I arrived there, and it was pretty noticable. I once drove a 1962 Dodge Lancer which had a Hyper Pak 4bbl setup and cam, but a stock exhaust manifold, It had a 904, 13-inch Bucrons, and ran 16.88 at sea level. 88 miles-per-hour.
Sixteens out of a 225 N/A in a B-Body at 2,500-feet altitude is asking a lot, I think.
