This car is very underrated Both the 1970 and 1971 hemi and 440 cudas had their HP underrated to help pass the governments test. This car has more like 550 HP with the hemi, and a 440 6-pack isn't far behind. 117 for a top speed is also low. You can push a hemi to at least 130, but not much higher if you want to stay out of the red. I am not sure about the 70, but a 71 hemi can get 0-60 in 5.6. Even today, this is one of the best super cars around, and the 71 can beat over half of todays 'super cars'.
