Hey Letllered 4.8, Every once in awhile. It will grind going into 3rd. But I think that's more of a sincro problem. At the track 3rd is your money gear. You can feel it pulling hard on top end at high RPM .. These little motors don't have much torque. So to get a good 60ft. leave at the highest rpm you can. Without spinning the tires And not bogging the motor. Walk the fine line!

I think the best mods would be: Long tube headers
good cam
computer tune
The best tires you can find. This is what helped me the most.


PM me if you have ?'s
