Question: Getting the most out of a stock looking ignition system.

His 1968 is a points car, so the "Mopar ECU to HEI module" conversion isn't an option. An "under distributor cap" type is the only option I know to keep the original look. Besides Pertronix, I recall a few others (Accel, some in J.C. Whitney catalog long ago). The Ignitor III is best, since multi-spark. The Ignitor II is also good. Avoid the original Ignitor since an older design that requires using your ballast resistor, i.e. equivalent to the old Mopar ECU.
