I think with a HEI they call to be gaped at .045. I you have after market like MSD and such you can open them up more. If you are running nitrous or lots of boost you wuld want to tighten them up.
Age old question
My combo below is running real strong!!About 1,000 miles on engine.Did a little tuning yesterday and it feels better than ever.I am going to replace plugs today.It seems to like the r44t and I have them gapped at a tight .045(hei ignition).Wondering if I should chage gap a little or stick with what I have??:thumbsup:Thanks
