To answer the first glaring question that's undoubtedly in your head, no, the 427 isn't really a 427. Instead, it's got a tweaked version of the Mustang's V8, so it's basically a Puritalia 302. But that really doesn't matter. Indeed, 445 hp in stock trim is plenty on a 2,500 pound car. And the 605 hp version? That's just sheer lovely lunacy.
