Crane HI-6 and PS-92 coil unless you can find an old MSD 10. I think FAST took over production of the Crane ignitions and Daytona looks to do them as well. It wouldn't surprise me if Daytona does them for FAST. Daytona does one also with a programmable ignition curve which would be my ultimate choice.
You’ll never believe this! But this is 100%. One of the engineers of Crane retired around the corner from me. He designed that ignition. Very nice fella. I stopped at his house while he was taking a delivery of a MGB convertible.
