I have 71 350-270hp with 350 trans and 2.73 gears. At 60 mph I am at about 2200 rpm. I would like to switch to an overdrive trans. What would be a good swap and how can I determine what my new rpm would be? Also I would like to be able to shift between the lower 3 gears, is that possible with the handlebar shifter? thanks al71
