Was at my buddies junkyard getting some parts the other day and he gave me 3 boxes of misc NOS spark plugs mainly Champion and Autolite. They all appear to be vintage racing plugs! Most of the Autolites say racing right on them. Part numbers Autolite BF703,BF603,AG203F and BF22.Champions BL57,N55T,UJ60P and J83Y to name a few. Any of you old drag racers remember using these part numbers? Gonna see if I can sell them to anyone restoring an old racer. The Autolites have the Star on them if that tells how old they are.
