Hey, I had a 63 Valiant Signet 300, with the 225 slant 6 and a pushbutton torqueflite. I can tell you that if you had 4 passengers on board and they all had $.50 to donate to the tank, you could go to the state line and buy beer and drive around half the night drinking it before you bounced off the bottom of the gauge. 22.9 cents per gallon, 15.9 during gas price wars...
