4L Copo SS/AAA only now
 

With the 4L Copo now rated at 593hp x 6 = 3558 +170lbs = 3728 lbs min weight for SSA/A I dont think the SFI spec's works now, is the car to heavy to race in SSA/A ?

593 x5.5 = 3261 +170 = 3431 lbs for SS/AAA on the new 9.20 index

Is this correct ?

Re: 4L Copo SS/AAA only now
 

4L COPO now falls 5.35 in the classguide. That means it can only add weight to fit into the 5.5 lb class. Would not be allowed to go to the 6.00 lb class.

However cars weighing over 3600 lb are fine as long as they do not go quicker than 8.50 et.
