I went with the Crane X-3000 setup in my 73. I was able to get rid of the points. Now there's one less thing to adjust. Also, I got a better spark going to the cylinders. I'm burning more gas in the motor and less in my exhaust. It was like I bought a new muffler where I didn't have one before.
You can also change the distributor in your car to a ZX model that has electronic ignition. Bryan Little's page tells how to do it. Heres the link, click on performance, its kinda near the bottom of the page.
