Engine description is in my sig.Wondering what auto lite plug would be best for my engine as well and a good gap to start with. Also what what total timing would you all suggest. I dont know if it makes a difference but i pull 5.5 inches of vacuum at idle on account of the cam and no power brakes. No vacuum advance but mech advance. MSD dist. part # is 8578, digital 6a box part # is 6520.
