O.K. I'm goin to make the SB motor, but what pinion should I use? I don't know how much torque or speed it has, so I don't know which one I should use. I want lots of speed, but alos a good amount of torque ( I don't want to have to wait 2 minutes for my car to get up to speed ). I don't care if the others beat my off the line, I just want to be able to reach some where near top speed in about 10-15 feet. Which one should I use?
