I can go 70 on flat ground at 10 MPG (awesome!) and when I got to the Rockies I was able to go 35 MPH up the steepest grades. If I had a taller gear to improve highway speeds I would have been going 10 MPH up those hills. Just think about it before you switch it. Bluebird knows what they are doing when they built these things.

I can hardly hit 70 going down hill. I have the same gears as you do, have you turned up your throttle screw? I am at 2550 RPM at 63.5 MPH and only get 8.9 MPH. Maybe I better start checking things on the engine, like fuel pressure or maybe she is just not broke in yet....3880 confirmed miles.
Thanks for all the feed back yall!
