Suspect kids numbers are BS, please help

the Z06 (505 hp) is crank no ? the Blackbird Earnhart etc all have advertised horsepower thats crank not rwhp ? or am I mistaken, don't mind if I am, but I just put 400 hp Manta on my SS and I am gonna feel damn foolish if it was supposed to reflect rwhp, that or I am gonna have to do LT and a small shot..
