Fuel economy

[Ross F-1]

It's a good day in an F-1 when you break 15 mpg. If you think a shoebox is bad aerodynamically, the trucks are like pushing a barn door thru the air, especially if not lowered and with west coast mirrors. But I managed to record 16+ on a trip going from 5300' up to 8000', with lots of up and downhill sections in between, averaging about 55 mph. My air/fuel meter was showing mid-13's by the time I got to the highest country, no better without going downhill. Since then I have made some changes to the Rochester and am hopeful I can improve on that. I'm running a 3.50 9" axle.
