I’m curious as to what others are experiencing in actual mpg. Please indicate the motor, trans, rear axle gear ratio, carb, ignition system.
My first mpg test with my restored 1977 F150 with a mostly stock 300, YF carb, DS2 ignition, C4 trans, 2.72 rear axle, driven for 160 miles on rural 2 lane roads, going from 2000 feet elevation up to 3000 feet down to 800 feet elevation and returned by the same route.
16.5 mpg
