According to GM, the NA 427/LS7 fits in A/SA, SC 5.3L runs AA/SA and the SC 5.3L with the bigger blower runs SS/AA.

I'm curious on how the NHRA horsepower "fudge" factors will be on the COPO.



Same as in the old days of yore. Takes a NA 427 Camaro in A/SA to be in the same class and contention as a NA 345 cubed Hemi Challenger DP.
