Cross-Country Road Trip in a '68 Barracuda

All I've ever needed going up or down the rockies is a little additional timing. I lived in the Springs a few years and would always have to change timing after coming down Raton Pass to the flatlands (69 Charger R/T). One other time in a 455 Olds 98 Regency the thing actually quit before I got to the top of Raton Pass, a quick timing adjustment and away we went.
