   The Jegs 555-40500 distributor does not work with a GM conversion.

Just asking, but what do you think you'll gain with the conversion?

 

[Bewy]

HEI will work with a magnetic p/up or points dist. What do you have?

   The Jegs 555-40500 distributor does not work with a GM conversion.

The Jegs 555-40500 is a revamped version of, and direct replacement for, the Chrysler production electronic ignition distributor, and it is designed to use the stock Chrysler distributor cap and rotor. It is intended to work with the stock Chrysler or equivalent replacement ECUs, can work with your Mallory ignition, and it will work with a GM-based HEI conversion if you decide to go that route.

Ironically for their listed question/answer, regarding HEI, Jegs own specifications, state this:

​

Distributor Type

HEI/Breakerless

If you read the link details, you will see that it's a Chrysler style ignition sold by Jegs. Magnetic electronic, just like stock.
