I installed an MSD Streetfire a couple years ago and ran it a few hundred miles with old plugs gapped at original spec and crusty old (original to the car) plug wires and it worked great! But I was already planning to freshen up the rest of my ignition…. Now, my engine is out of the car for rebuild (due to broken dilaver studs). I searched and read a lot of old posts on this forum and saw various recommendations. One guy on this forum (tirwin) seems very knowledgeable and he has the same year car as me - he recommended .045” plug gap. So that is what I am going with, at least for starters. I also have a new set of Clewett Engineering wires, NGK plugs, a new Bosch cap and a special (and cheap) resistorless rotor that was also recommended on this board (By John Walker, I think). The rotor I got at o’Reilly’s is part number 12-0101. But I think this was based on a cross-check lookup of some other part number I had found on Pelican message board. Anyway, the O’reillys auto 12-0101 rotor works great.
