Not Ranked
One of my friends here in Dallas also has a KC 496 with hydralic roller in his SPF and his made 554 RWHP but it was dynoed when it was 50 degrees and no humidity. Humidity is a big kill factor on the dynos but a lot of guys that have dynoed their Cobra seem to loose 20 to 25% from the crank to the wheels. I had a SPF 6 years ago with a 427 small block made 638HP at the crank and 465 at the wheels which was 27% loss but we thought the single stage clutch was slipping a bit. I extremely pleased with the 530HP at the wheels with the conditions. The car is carbon fiber and with the aluminum engine is only going to be about 2,000 lbs so this much HP is way over kill anyway. At the end of the day it is what it is and I agree with others that different dynos will probably give you different results. I really put it on the chassis dyno to dial in the air fuel mixture through out the band as I'm much more concerned on having that correct vs the HP...........
