Ford has a long history of under rating their horsepower ratings. It may be rated at 20 hp difference at the crank but it is more if you compare how much of it makes it to the ground.
After searching youtube I found that most stock 13-14 GT500's are putting down 600whp+ vs 520-550whp for ZR1's on a chassis dyno.
