Points to electronic ignition for a 318

I have used Pertronix and had no issues. On my Dart it had an MSD distributor and an orange box and that worked well. Then I went to the MSD dizzy and an MSD-6 ignition box. That worked great. Now I just bought an MSD 6AL-2 programmable ignition box that I have yet to put in. I expect to have a lot of fun with that. Basically, there are a lot of ways to go, all of them will work, and some better than others. I would take into account what you have for a motor, what you plan on doing in the future, and what your budget is. If you want to go cheap, Pertronix works very well and is way easy to install.
