My Dart Swinger Project!

Man that i didn't know! I'm demoted back to newbie after all this! I had worked my way up to beginner but now I'm bumped back down lol.
All jokes aside you may not be wrong about the plug wires. I didn't like how they fit on the distributor cap at all. The spark plug ends was nice and tight with a good positive snap when they went on the cap end not so much they boots where very hard to push down over the cap and there was no connection feel. I didn't like it but thought it would be OK. Maybe that's my problem.
On some wires you can push the seal cap up the wire a bit, expose the end connector n hopefully feel it click in. My inlet leak was between tube and flare nut. Check male and female flares for gouging. Clamp on twist hones are available to eliminate gouges. Keep going and good luck!
