Pertronix elec ignition

[Rich69shortfleet]

I have had the Ignitor I on my Chevelle for over 20 years now, haven't ever touched it, it works great. I put an Ignitor II distributor in the wagon, never an issue for 5 years now. On the GTO I finished a few years ago we used the Crane XR-i and it has also worked great. It is like the Pertronix set up, fits under the stock cap but eliminates the points. The extra bonus of the XR-i is that it also provides a rev limiter which is a really good idea to have on that Pontiac engine as bad things happen to them easily if they are over revved. It cost the same as the Pertronix, so if you have a need for a rev limiter be sure to consider the Crane version.

The only downside to these under the cap set ups is that if they fail you can be left stranded as they are rarely a part you can pick up at the local parts store. I always carry a spare set of point in my cars in the event I have a failure I can pretty quickly and easily reinstall the points and go on my way. By the way, a matchbook cover is about the right thickness for setting the points gap, at least close enough to get you home.

I've had an HEI in the truck for just short of 20 years. Never a problem until recently, still trying to track down the source of the issues on that one.
