Dont worry,being a guy,I feel I sometimes ask questions that I should know also,its all relevant.:toothy10:Ive worked on and been around older cars my entire life,I dont know everything about them but I love learning.
But as to your question,I put Autolites in my 360 Duster and runs very good(gapped at .35)
And as far as Champion plugs go,Ive used them in my GLH Turbo,a bit colder ones for the 6 years Ive owned the car and never had problems.I guess its a matter of personal preference maybe?By the way,nice Dart you have ,you did a nice job
Good luck!:cheers:
