You'll need a very big spur gear.

+1. That'll not only get your ratio closer to where it should be with your current gears but it'll allow you to fit a smaller pinion. That Genesis is a big, heavy truck and I'd personally gear it for about 40 MPH and go from there (watch those temps!)

When the bigger CC motors come out, I'd look into one of those if I were you. They should be able to handle the load of the larger truck better.
