rc10t 40mph?

For 2s, I would say a 6s or 7s 540 feigao. They are more powerful than the mamba max motors.

On a side note, I have a 540 6s motor that has 1 run on it. PM me if interested. It has a kv of about 6000 and you could gear it to what ever speed you want in that truck. It is lower kv than the 7700 mamba motor, but it has a longer rotor and will produce more torque than the mamba motor and will run cooler.
