3:55 gears to 323 gears

Without my knowledge, the vacuum advance during my road trip in the '65 Formula S (318 auto) was disabled and MPG were very low. Ran out of gas in a very remote area of Mexico, just having passed some people selling fuel in 5 gallon containers on the side of the highway. My spouse was following behind me, so she turned around and bought some gasoline at black-market prices.
