I have a new zx dizzy with a e12-80 module on a stock L28 motor with 4 bolt su carbs. are these msd 6a worth putting on or just leave the e 12-80 on thanks

I've heard nothing but good on the E12-80 module. I'm still running points, but if the change comes, it will be with the E12-80.

You can use a MSD6a with an E12- 80 dizzy ,and you will have to also have to add a tach adapter. You may not notice any changes from an already proven setup. I,m running the MSD on my 74 260 to replace the factory transistorized ignition
