converting over to HEI iginition (wiring help)

Hi folks I am installing a 383 in my 68 vert and will be converting over to HEI iginition, my engine builder says it's as easy as hooking up the +(pos) wires from the old coil, to the + spade connector on the HEI. So should both original wires the one from the key and the one to the starter be joined to one connector then plugged into the positive lead of the HEI?
any advise would be great.
Thanks
Jeff

Your builder doesn't understand HEI. The HEI requires a full 12 volts to its (+) terminal, and your current coil feed wire is a resistance wire that only delivers about 7-8 volts; you need to run a new wire from the "ign" cavity in the fuse block to the HEI so it gets a full 12 volts, or cut off and replace the existing resistance wire with a regular wire from its terminal in the engine harness connector.

The original wire from the ign. switch to the coil is a resistor wire. You don't want to use this with an HEI. You could splice a section of wire in at the bulkhead connector and eliminate the resistor wire or do what I do. Tape up the original wire and hide it, then run a new wire from the IGN terminal on the fuseblock to the BAT terminal on the HEI. This way you can go back to original without any hassles. A piece of 12 or 14 gauge works fine. You won't need to hook up the wire from the starter to the HEI.

Didn't type fast enough. What he said.

is the resistor wire the portion where the cloth braided insulation bends and is bare, and covered with a rubber band or boot type deal? Also for the starter, I only need to connect the big cable from the + of the batt and what to do with the other two, one coming from the old coil can be dumped, then just hook up the other remaining wire?, can I also just find the resistor (I hope it's what I described and not a fusable link or something,) and cut it out before the loop and then just extend the wire to the HEI (batt term)
thanks
Jeff

I used a crane fireball set-up it goes in the points dist and does away with the point. No need to beat on the firewall and keeps that stock look.
