You guys need to look at the history of chevy. You're not going to get it all, the 1st year out. Then there will be nothing to sell the following year.
So, look for a 100hp jump from the standard V8 for the Z28. In a year or 2 they'll up the hp some more. The Corvette will be dropped in a couple of years and the Camaro will then be pulled out of Canada and will finally become American Made, where the Corvette was once built. Not exactly what I want to see happen but my crystal ball is pretty accurate. |

The LS3 in the Camaro produces less power than the same LS3 in the Corvette. My guess is 565ish HP. |

Ford will just have to figure out how to put 2 superchargers on the GT500!

Even if GM did keep the Z/28's output under that of the CTS-V by restricting airflow, it just means you'll be able to rework the intake/exhaust and really open it up.

Between 580-600 horse, IMO.
I don't really believe GM is going with power between SS and CTS-V. I see many photos with the GT500 in prototype testing, therefore I'm thinking that is the target. Having said that, in order to be competitive now, I believe Z28 has to at least match the GT500 where it currently is. However, I believe the GT500 is going to get a bump by 2012, so I think GM will try to look ahead, bump it closer to ZR1, so it's not going to see a huge spread, if any, should it be a significant increase from the serpent. It has to make up for the weight, which I believe will fall in between SS coupe and convert', so I'm a little torn on how to propose it will get there. Since I've read CTS-V's exhaust is quite conservative, and it being a luxury car, I believe their are restrictions that can be relaxed for Z28, resulting in a small bump from LSA level. It appears the intake and exhaust systems might be a little less restrictive when the V6 goes from CTS to CAMARO, so that's another little bit of support to me. In addition, the quad tips suggest dual-mode exhaust, like those featured on the Y-Bodies; another opportunity for a bit more power. It certainly sounded better in those videos at the 'Ring! A new upper intake plenum suggests to me there's a little more development between LSA and LS9. Because the upper plenum doesn't appear to be as flat as LS9, maybe there is a little less restriction, so perhap we could see a 2300 running 1900 psi levels (10.5 to 9.0, respectively) and make the power I'm suggesting. It'd be nice to see an upgrade to the short block, for the pistongs and rods. I don't think Ti rods are necessary, but it'd be nice to see the forged slugs from LS9 carry over, and maybe some forged H-beam rods from the GMPP catalog. I'd like to see LS9's cam come over, too, since it doesn't have to be conservative, like one would expect in a luxury vehicle, like CTS-V. It'd be nice to be able to grow, safely, to 600-650 RWHP, like the GT500 can (and more...), but I can't complain, too much, knowing that if GM releases a 600 horse' Z28, it can't be pushed to 700 horse' with a little pulley, CAI, and exhaust upgrading/tuning. I'm just crossing my fingers the chassis tuning will match the power in terms of performance. I'm sure we're going to be adding weight, so I hope GM can find a way to control it

For those of you who are still unsure about the LSA going into the Z-28...
