Man... just read through all of this. Who cares if there may be a Z28 or not? Who cares that the new Corvette is out and looks like a Nissan GTR did the dirty with a 5Gen Camaro and there you have it? Why not just build what you want and call it a day? Why not take the best of what the ZL1 offers and build your 2SS up to it and surpass it? Why does it have to be called a Z28? Just make something, call it what you want and be done with it. Hell, that's half the fun of owning a car that is an excellent platform to to build up and personalize. Anyway, I don't know anything. I just think with all your energy you could have made your own Z28.
Just love the Camaro you got.
