My motor came with the coil over plugs, but i took them off and used my MSD coils and msd wires, that way i didn't have to try to find out how to do coil over plug set up. The swap is easy, lets just say, i did the swap by myself, at my house, with a cherry picker and jackstands. my wife and friends can vouch for that.
