Guys,
I have a 69 427/390 and I'm hoping some of you might have recommendations on spark plugs for non-judged driving. I can install the correct ACs for judging, but I would like to drive this car some so your thoughts on the best currently available spark plugs would be greatly appreciated. Anyone think the newer Rapid Fire AC plugs are any good for normal driving vs. conventional plugs?
Thanks as always,
Brad
