If for 2012 the GT500 gets the TVS blower and goes to or around 600 HP..then look for a reaction out of the 2012 Z/28 (or 2013)

Even if GM were to use LSA straight out of CTS-V, there's still the problem of the upper intake not fitting below the cowl. That's not to say that they simply can't engineer a lower-profile lid and stick with that, but the intercooler might very well have to be altered, so why not look into another SC, like the LS9's 2300, which profile is a lot lower? Maybe run with lower boost so as not to tax the hyper' pistons, PM rods, and cast caps, among the many other differences. I believe GM should be looking as close to 600 as possible. Some will point to the 'Vette
only having 40 horse more, however, I believe ZR1 will be ready for another boost (pun intended) in the next year or so, so... the door's open for Z28, IMVHO.

580 here
I'm hoping they look a little farther into the future and put out 600, but there's nothing wrong with 556 either. That's nothing a little simple intake and exhaust can't change, or a little pulley and tune
