I've always run Autolite number 85 in 440's just wondering if i might need a different heat range with this set up.

I quit useing Champions 25 years ago when i couldn't keep a set in my 12,5 to 1 440 more then a week before the tip burned off. My local speed shop recomended the 85 Autolites and i've used them ever since with out any problems.

I would try Autolite # 84 I like my plugs cold, not like my women Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
