2 ideas. one whats your base timing set at?? should be about 10 deg. btdc with the shunt unplugged. 2nd in my truck with the cam i have in it i was running regular stock pluggs.(Autolite) it didn't feel like it should so i switched to Autolite platnium. what a difference in the way it performes both cold and fully warmed up. maybe not your problem but worth a try
