    Major tune up

    I ordered the iridium spark plugs, American racing spark plug wires ,MSD distributor cap and rotor and the MSD coil all at once . The wires were all cut to length and numbered for easy installation .Do one wire and one plug at a time, transferring each plug wire to the new distributor cap . I took my time ,turned the heater and radio on in my garage and i was good to go , probably a couple of hours . I fired that baby up and took it for a ride, all i can say is wooow !!!!!!! Get rrr done !! Thanks America Muscle --- from Canada have a nice day eh .
