It is supposed to be 500 hp 500 torque but it has not been on a dyno so I don't know. It is more power then I can use with street tires. It can put on a real good smoke show and no you don't need to use the brakes. Just put the pedal down any time under 25 mph and the tires are blazing. Feels like a hopped up big block is sitting under the hood but without the weight. It can get kind of hairy some times, almost lost control once or twice, now I am a little more cautious. I have had it up to 80 - 90 mph at full throttle and its pretty scary; the body of the car is torquing and it pulls real real hard with a loud roar coming from the 4 barrel. It feels like it wants to rev forever. Real happy with the power.
If you go to my profile's photo gallery I have the cam specs, compression etc listed there.
