Make sure you have full battery voltage to the HEI. And the voltage stays at battery voltage while you drive.
You don't want to use the ballast or resistor wire that is used on a point type distributor.
Possible bad connection or ignition switch has a poor contact.

Also be sure the battery is being charged by the alternator. If the battery voltage drops, the spark will be weak.
