I can see why Chevy might not want to use it. Some people feel the SS should be top dog and not the Z28, and the Z28 was originally a track package with a high revving motor. So I can understand them not wanting to just use it because they have it. I can see them using another name for now and then when the 6th gen Camaro comes around they can reset the order. LS->LT->Z28->SS->???
What ever they call it I'll still lust for it.
