In this thread:

Twin plug ignition???

Grady Clay describes using the drive off the left cam bank to rotate a spindle holding a disributor rotor inside a screw down distributor cap. The rotor simply distributed the spark. From what he said, I deduce that the contact of the rotor was very long to make up for the lack of timing advance in the secondary distributor? I would like to explore that.

In the same thread Henry Schmidt showed a 962 distributor that did the same thing.

From what I see so far this is a doable project.

Good luck
David Duffield
