Don Stocker stated..The last couple weeks I've driven my '50 Chev 500+ miles and averaged 20 mpg. Its a 216 w/3 speed and 4:11 rear end gears. I realize that a car will slide thru the air some better than a truck but still a close comparison.
with 4:11 GEARING, that is really something but if you say it is true............then..
