What I did to slow my car down to run 10.0
stuff was put a mech throttle stop on it and
lower the launch and shift rpm... you can also
slide your throttle cable in so you only open
the throttle part way... if you change gears in
it you will be WAY under your torque point and
be forever in low gear... I used the trottle stop
on mine so I could run 2 classes and change over
quickly.. this is what I built to fit on the carb
