How tough are Corvettes? When to engine and driveline parts start breaking?

Corvettes are admirably strong. So far, nobody seems to have made more power than a stock block can handle staying naturally aspirated. Only mistakes such as running lean seem to do the LS1 in. Forced Induction cars seem to be happy until around 550whp, beyond which things can get a bit sketchy. As far as the rest of the driveline, the clutch is the weak link from the factory, which is fine. Once that is strengthened, the driver's side output shaft in the differential is notoriously weak. When you have your 3.90 or 4.10's put in, have a stronger shaft installed for another $300 or so.

But, that is with hard launches, lots of horsepower, and extremely sticky tires.
