I don't remember what years ??? it is easy to test for tho...
.
a points setup/coil runs on 6-9v thru the ign switch and resistor wire,,
12v from the starter is just for cranking,
due to the starter load, ign switch voltage to the points/coil would be much lower..
.
x2 if you swap to a HEI?? it needs full 12v all the time, to work right...
the resistor wire will trigger a relay tho, [if its on during cranking]
a relay mounted under hood with battery voltage to the HEI is a good upgrade
to un-load the ign switch and interior wiring too..
.
if you do swap to a HEI, get a spare Ignition Module for the glove box,
and don't buy the cheap ones,, get a ACDelco..

good pitcher Sean
