Even a purely stock, older car should have an HEI or some other form of electronic ignition. They range from "drop-in" assemblies to the more complicated models, most of which are fairly easy to install. What you get is less maintenance and great drivability. Some can be installed to look like a vintage distributor; others are readily recognizable as upgrades. Of course, while doing that, upgrade the wiring and plugs, too. When it comes to a manufacturer, take your pick. Just by flipping through the pages of SC, you're bound to find dozens of ignition companies with an application for you.
