What’s the best/worst mileage you’ve ever achieved? Before I properly tuned the carb in my 1969 Chrysler, I was getting about 6 mpg from my 383. (Now I get about 12) On the flip side, I was once able to get 53 mpg from my 1.3L Suzuki Swift GTi. I don’t know many other solely gos powered cars that can do that well. What about you guys?
