Who is BS'ing who?

When I was in college during the "fuel crisis" of the early 1970s, I drove from Daytona Beach, FL back to home on LI. I-95 was not yet complete and the gas stations on the new parts of the interstate were few and far between in the Carolinas at that time. There was a concern that not many of the existing stations would be open all night and I did the drive without shutting off the engine for 22+ hours.

The car: 1968 GTX, 440, auto, 323 gears. All stock. Fresh tune. I had a set of Goodyear G70-15s on the rear for the trip. I bumped the secondaries to not open until about 65 mph. I had put Hedman Hedders on the car between semesters, but did not have enough cash for mufflers, so the only exhaust system on the car was the headers.

Because I wanted to get as much mileage as possible, I drove the car like there was an egg between my foot and the gas pedal. I kept the car at no more than 60 mph so that I could gage my progress by mile markers (1 mile per minute) to get an idea when I would reach the next town. I kept a miles/fuel log religiously.

The bottom line is that I was making about 400 miles per tank on the flats through Florida, Georgia, South Carolina, and North Carolina (I would start looking to gas up when the gas gage needle read 1/4 tank, however many gallons that indicated). Mileage decreased a little in the hilly areas of Virginia and again when more traffic appeared on the road in the northeast section of the trip from about Richmond, VA to LI. My computed mileage was around 20-22 mpg average for the trip through the flat lands on the over night part. I still might have the trip log somewhere.
