Gap should be set at .035, not .040. BTW, in stock form..you won't see any gains from 89 and 91. Unless you have a custom build. I run 89, to help stop some pinging. When it gets colder, I run 87 or 89.
Keep it Mopar, buy Mopar Parts.
I am completely disgusted every time I think about having to take a distributor cap off of one of these trucks -Screamintrashcan
