SB motor w/ plastic pinion

[GhettoFiedRacin]

I put my SB motor in my car with a temp(or so i thought) 13 or 14 pronged plastic pinion.JEEZ!!! It flys up my STEEP driveway the same as the stage 2s i cant EVEN control it on flat ground. Also the locked diff is a big help with my speed and accel. I got the pinion out of a toy drill .... it had the motor type from the SB (same company at least). ITS NICE
