Fern and all I had the same experience when I did a bench test w/ Pertronix installed in my 57 300 distributor, no spark. I tried a second unit I had for my 57 Imperial. Same thing, no spark. I called Pertronix and talked to chief tech. He asked if I could send him the distributor so they could analyze. He reported back that they found the plastic rotor was not seating all the way down over the cam lobes. They tapped it down and it worked. When I got it back I put a large socket over the top of plastic rotor and gave it a light tap. I could see it seat. Bingo it worked. They sent me a free unit for my trouble.

We have tried to install that kit in my 1962 300H and cannot get it to work. Is there a special way to index this unit to make it work? Any help would be greatly appreciated. Who is the member on this list that sells these?
