I could be wrong ,but I'm in the middle of finishing up my rewire job under the hood. The previous owner had installed HEI; I replaced the motor and did some other upgrades.In my rewire under hood, I found that the HEI was wired to the balast resistor< never seen this type before,round> and did away with the resistor only to find that its only getting .8 volts but runs... this should had 12 volts? correct?
Doug, you are correct. you can take the wire from the starter out and remove everything from the Dist out and put you HEI plug on the wire from the fuse box side and that is it. You will have 12V there and if not you have some other problem. Good luck Jerry

You will need to eliminate the resistor wire in order for the HEI to work correctly. 2 ways of doing it is to just run a wire from the fuse box from one of the 'ignition' spots or replace the resistor with a new wire. That is what I did with mine. I removed the resistor wire and replaced it with a 10 guage wire. I didn't know mine still had the resistor until I checked it with a multimeter. The distributor was only getting 7.55 volts. Some of the things I noticed were heavy cranking on the starter to start or it would not start at all.
