The HEI distributor is an inductive-discharge-style ignition, but with the points replaced by a solid-state switching device called an electronic ignition-control module.

To ensure that the test was fair, we had to make this distributor as good as new, or better. So, before it ever saw action, the stock distributor was treated to a new rotor, cap, and module.

In these HEI ignition systems, the points were replaced with an electronic ignition module and a magnetic pick-up assembly.

If you're swapping points to an HEI distributor to lower maintenance requirements, you're good to go, but will you be able to feel a difference if you do?

In contrast to points, HEI ignition is considerably more maintenance-free. The task previously accomplished by fragile points is taken over by a reliable solid-state electronic module that can ...
