108 Electronic Ignition
108 Electronic Ignition
(Also applies to 113, 111, 109 etc...)
In my 250S I have been running this combination:
- Pertronix kit
- Plug wires with metal beru ends (if you tell rusty 1968 280S, you end
up with the correct set with the 90 degree end for the #1 cylinder)
- Bosch copper plugs
- Bosch "Red" coil
- standard bosch cap and rotor.
Modifications made were very minor. A bit of the Pertronix adapter
plate in the distributor was ground to fit correctly, and
you need to sand off some of the material from the bottom of the rotor
so it sits low enough on the shaft not to interfere with the cap. I
also bypassed the ballast resistor that was necessary with the original
coil and points.
My setup has been running for 2 years and 18k miles now without any
issue at all. The engine holds a steady ~600rpm idle and runs to 6300
redline without a miss. I think the setup is pretty much what Randy
recommends when using Pertronix.
