Personally I'm glad they dropped the bogus down-rating of motors in non-Corvettes. In the long run it will result in more powerful Corvette motors.

They put the ls1 engine in last years GTO so putting the Ls2 in this years GTO should not be surprising. Remember the CTS V is using the ls6 engine that was in the C5 Z06. As for the Ls7 engine being used in other cars that remains to be seen. The C6 Z06 is more than just engine alone.

None of this makes the C6 less of a car than it is.
I own a 2004 CTS as my daily driver. This car listed for $32,000.00 where as a CTS V lists around $20,000.00 higher. I realize the CTS V is more then just a different engine but that's a pretty big hit upgrade. I would think if they ever decide to make a super GTO (LS7) the same would apply. I would think the average buying age, a Corvette compared to a GTO is probably 10 to 20 years older? Maybe someone out there can confirm media age for each car?AL

The C5 was legitimately rated at 345hp (later 350), the LS1 F-body was SUBSTANTIALLY under rated at 305hp (later 310, with SS/WS6/Firehawk models always rated slightly higher though they were in reality putting down very little, if any, more hp). LS1 F-bodies often dyno very near and in some cases at or above their rated flywheel hp/tq.
This is basically common knowlwdge at this stage of the game.

just wait.... i bet the 427 from the new Z will end up in other cars such as the GTO or even the new Cobalt. i think that would be a kick in the face but if they put the 427 in a light car then why buy the corvette?
thinking about the 427,the Cobalt with a 427 would sure be a sleeper, and they are not a bad looking auto.
