I knew I would forget something usefull about the car; It has no front suspension, using fabricated spindle mounts (3-point contact to the chassis), and no front brakes. We have the wheelie bars, which are the bottom-flat-bar style, set on...

RPM drop vs. rear gears vs. stall speed, please help

A little background on me; My dad bought a used race car last year, and neither of us have ever had a drag race car before.
