Does anyone know if there is any kind of horsepower gain with the MSD C.O.P.'s? I'm looking into getting them, and i know in 5.0 and SF they did an install on them and they seemed to give about a 10HP gain on the car they used but it was a SC car. Mine just has the normal bolt ons and i didn't know if they would give that much of a HP gain on a bolt on car.
