GM's engines, notably their V8's, are generally pretty mild from the factory. More so than most other manufacturers. But that also alows for a very cheap build up for those that are interested. From what I understand, a cam swap and intake and you get LS3's up to nearly 500 hp with parts from GM's own catalogue. So they can bump the rating up to 450 when ever they want.

That 436 hp rating comes from the optional exhaust that you can get on the standard C6 Vette. It sounds rather tame during regular acceleration but under WOT the pressue makes butterfly plates flip and making the Vette sound more aggressive. Forgive me if you already knew that, I figured I'd just put that out there!
