I guess the era of the once quality made AC plug is over. Time to adapt. I have had pretty good luck with Autolites on my small blocks. I assume they would work ok on my inline. A little trivia TooMany, F___d used a Quadrajet on their Boss 429 to meet federal emissions. And Pontiac used a F___d top loader 3 speed in the late sixties as their standard tranny. Sorry folks got off the subject.
