Sorry, I should have paired it with my other post. Its a 410, MP .557 cam, 9:1 comp, hooker headers, 2 1/4 dual exhaust out the back, turbo mufflers (me thinks, I didnt have the exhaust put on the car and I dont fully remember) It is more rumpity as the cams quite a bit bigger but i dont consider this all that radical by any means.
