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

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.
