Fireside Valiant chat

I remember traveling when I was a kid from Colorado to Washington (maybe 1980?) in my Dad's '68 valiant. We were low on gas, so low that it looked as if the gas gage didn't work. We thought we might run out of gas, it was late at night, but that /6 1 bbl kept going till we finally found a Casey's that was open.
That same valiant raced one of my older brothers Mercury Cougar with a 351W in it on I-25. It was a top end race, and that cougar could not get by that /6 :D
