Re: Converting coil style ignition to HEI........what is involved?

Can't edit post #3 so I will finish the last paragraph here.

What I started to say is that if the hot wire to the coil /hei still has 12 volts when you are cranking you can just extend it or run a heavier wire in it's place. There are some early style ignition switches that don't run power to the coil when the key is turned to start as they rely on the resistor bypass to carry the power to the coil when the starter is cranking the engine. That is just something to be aware of in the swap. The easy fix would be to run the bypass wire even though it doesn't have a resistor to bypass now.

Some ear
