390 hp @ the crank has been what the dealer told me. They had them rated at 376 HP because they did not want to get too close to the 425 hp of the SRT-8 for only 35 hp more and $5000.00 difference in price. I know that you get more than just hp from the SRT-8 and that means alot. But for some people its all about horsepower. So yeah Mustang and Camaro boys... we only have 376 hp.
