Re: Champion Spark Plugs on a L-79 Corvette?
The only mechanic who could get my 1969 Z/28 to run right said that he wouldn't use Champion plugs in his lawnmower. He replaced the Champions with AC R43's. I used Champions in my 1965 Dodge Coronet though all the time, and they seemed to work fine in it. Maybe Champions just work better in Mopars than in GM's.
