What is the mpg on a 1953 flathead v8?

The fuel efficiency, or miles per gallon (mpg), of a 1953 flathead V8 typically ranges from 10 to 15 mpg, depending on factors such as the vehicle's weight, driving conditions, and maintenance. These engines were not designed with fuel efficiency in mind, focusing more on power and performance. As a result, modern vehicles generally outperform them in terms of mpg.
