Don't sweat it..... Before my 57 300C was taken apart 3 years ago, I lived in Stanley, Idaho at the 6300 foot elevation. The car had been tuned in Albany, NY before I drove it to Stanley. Once I had it in Stanley, I drove it numerous times over the hill (Galena Summit 8700 feet elevation) to Sun Valley which is about 5500-5800 feet elevation without a struggle going over the mountain and without the engine loading up. It is likely you won't even notice a difference in performance unless you were at a dragstrip with timing lights. Remember, the general population drove these cars over Donner Summit every weekend to go to Reno from the SF Bay area and Sacramento back in those days.
