People need to use the brains God gave them and look into past performance cars to find the answer to this question. The new engine is most likely going to be the LSA, and it will only make more power than the 556 HP the CTS-V has, if the intake and exhaust are slightly more free-flowing. I would guess a 10 HP bump to approximately 566 HP.

GM has absolutely no reason to push the limits of the motor more than they already have (and for less money, even).

This new Z/28 doesn't need 600 or 800 HP to be competitive and beat the GT500 performance numbers. It just needs high quality, wide, and sticky tires (read: not Goodyear F1s) and a great suspension setup for the roadcourse.

Sound thinking - if you look at what GM has done with the vette - it typically comes out with good horsepower but they always have tricks in their bag to bump it up over the next several years to keep the public interested in buying it. So, I expect it to come out with 575 or less.

It they change the platform as I have read on this forum and it becomes a smaller car, there won't be much incentive to raise horsepower a lot.
