something else to check on, when you convert to electronic ignition you need to upgrade the voltage regulator. chrysler has a specific one for single ballast resistor cars
i wouldn't use that on the street.. yea i know a bunch of people do but the constant output would worry me. especially with a stock wire harness... convert to a stock dual fld regulator and be done if you covert at all.
Constant Output Voltage Regulators
To ensure your ignition and electrical systems can provide maximum performance, install a Mopar Constant Output Voltage Regulator. Voltage is held at a constant 13.5 volts. For race applications only.
