I believe it's because the Vette has a different tune and a different cam although I don't remember. I wouldn't rule out what Scotty said either in that it's just a paperwork thing, after all it wouldn't be the first time GM did this.

Corvettes are available with two exhaust systems (one a form of cut-out). The less restrictive cut-out system is rated at an even higher horsepower. I know that the power is measured at the flywheel, but believe that the exhaust system is also a factor.
