The HEI conversion puts the coil in the distributor cap most of the time, that’s why the distributor cap is so large.
As for a ballast resistor, it is not needed if the coil is designed for full voltage both starting and running. That’s a question for the manufacturer of the kit used - if a ballast should be used or not.

I recently switched to a hei distributor and removed the "lean burn" spark management method. What exactly does that mean in my 1979 Dodge Magnum? I noticed that the ignition coil and ballast resistor are both missing. Any assistance would be greatly appreciated.
Why on earth did you remove the Lean Burn system from such a rare car?

99% of the time, the computer is not the problem. Did you do any diagnostics at all???

Since it's a Mopar HEI conversion does it have the small cap and separate coil? You just need to route your start and run wires directly to the HEI coil, dispensing with an ignition ballast, as HEI operates on full system voltage.
