Like Macros mentioned, your 2 speed may be shifting too early. Can the car achieve top speed on the back straight with the other cars? If you can, then the 2 speed may be shifting early. Tighten the screws in the 2 speed shoe. If the engine screams at the back straight to get up to reasonable speed, then your 2 speed is not engaging. Loosen the screws in the 2 speed shoe.
The 835 or the 705 shoes have heavier springs in them. Other than that, everything else is the same. Heavier springs would cause more problem for the 710 in your case.
