"While this isn’t a match for the 638hp (475kW) output of the supercharged ZR1, the Callaway Corvette is still capable of reaching speeds in excess of 200mph."

If 580 bhp isn't enough, the Callaway C16 produces 650 bhp, and the C16 Speedster makes 700 very streetable horsepower.

"At the customer’s request, Callaway will also install a hood decal that matches the design of the tuner’s 650hp (485kW) C16 custom speedster."
Actually, the center section of the hood is painted a contrasting color. That's part of the package's standard equipment. There's no hood "decal".
