You have to remember, any time forced induction [ie, boost] is entered into the equation, you're basically adding cubic inches...remember the old GM rating system for their blowers (6-71, 8-71, 8-53, etc)...they represented # of cylinders/cubic inches per cylinder they could scavenge.
I was under the impression also that AA/S was created with the new cars in mind, and if the old stuff fell into it then it was all the better...but throwing the new CJ's into A/S is a joke...the amount of weight they're gonna have to throw at that combo is gonna have to be equivalent to a co-pilot!
[I'm just jealous GM isn't the guilty party here...]
