From the rulebook:
SS/CM - 9.50 to 10.49 lbs per CI - 2850 lbs minimum, includes driver.
SS/DM - 10.50 to 11.49 lbs per inch, - 2950 minimum

Jason,

Thanks for the reply, one more question however; what is the rule for the carb and do you add the 170 to the weight amount after you do the math with cubic inches to the weight break ie: 300 ci x 9.5lbs = 2850 + 170 = 3020

You don't add 170 lbs for the driver for the modified classes. Actually, it's just the opposite if you run an automatic transmission you can deduct 5 % from the total. In your example it would be 300 x 9.5 = 2850 x .95 = 2708 which I think would round up to 2710. Hope this helps.
