George, we took delivery of our Chevy Suburban with 454 engine and a special rear axle ratio of perhaps 1.5 (for trailer hauling) on the day before America's gasoline supplies dried up completely -- was that 1963...? The car did 6 mpg, so Chevrolet very kindly included a 30 gallon gas tank ... we hadn't worried because gas cost about 35c a gallon then. Jimmie immediately changed the engine to increase the mileage to 8 or 9 mpg. I think he removed the vacuum advance on the carburetor and installed a centrifical something or other -- but I'm a bit fuzzy on the details. There was no gasoline to be had at the pumps. Spontaneously one or another gas station would open up for an hour or so, and would limit the cars in the instant line-up to 5 gallons or some such. My laundry man would keep his eye on the BP station across the street from his shop, and would telephone me to bunny it down when he saw them opening up. I'm 1.1 miles away, and I would tear down to get in line. The biggest question then was am I better off idling, as each car ahead of me got its 5 gallons, or am I better off turning off the engine and then on again, as the line crept forward. We never got a definitive answer and so I ended up idling. Aah, the good old days ........
