20%  For a 2-speed Automatic Transmission (Small Blocks)Figuring out your Weight:
This might seem to be complicated, but it really makes for very competitive racing!!! First of all, you need to know how many cubic inches your engine is and a calculator to make it easier... For example you have a 550ci Big Block(3125lbs) with Sheet Metal Intake(+10%), Dry Sump(+10%) and a Power-Glide Transmission(-15%) Total up your weights adds and subtract your weight deducts....You would take your Cubic Inch multiply by the amount Adds or Deducts and come up with your PSCA Race Weight......Example for above... Add 10% + 10% - 15% which equals a total of 5%.. Take that 5%x 550 which equals 27.5lbs, add that to your 3125 Base Weight (27.5 + 3125 ='s 3152.5lbs) Your SCSN RACE WEIGHT WILL BE 3153....We will round up all figures to the nearest pound.. If anyone has any trouble figuring out your weight for your combo, you can contact Mel at 661-917-3078 and I will assist you...
WHEEL BASE:
Must retain stock wheel base with a maximum variation from left to right and front to back of one inch.

WHEELIE BARS:
Wheelie bars permitted
