Yeah I really think with that motor, gears won't be an issue. I'm running 4.37s with 35s and carb. My efi in the runner has so much more power-that's why I want to have both running efi. Even with the carb, it doesn't do to bad. It's no hill machine on the hiway, but it will do 70 just fine. Wheels like crazy with the dual cases too.
