Howdy,
I've been thinking of upgrading the ignition on my '80 Fiesta S. I am currently running the stock Duraspark unit and an upgrade Bosch electronic distributor. I don't know much about the different types of ignition boxes like MSD boxes and the like, but I'd appreciate any information anyone cares to share.

Also, thank you to Fiesta Frank and others for responding to my question about the Fiesta heads.
