Re: 59: Electronic ignition upgrade?

Somewhere on the net there is a how to on that.

Here is one tech tip on it Photobucket blurred the photos because he didn't pay the premium to be able to share them but his instructions are pretty clear. Primarily you need to remove the flange from the HEI that holds it down in the later engine so you can use the clamp from the 235 to hold it in place but use the advance on the Hei.

Pretty simple to do and even there parts should be available for the HEI https://www.chevytalk.org/fusionbb/s.../fromsearch/1/

Guys this is where your Pertronix (sp) won't work because he has no ready sources for parts where he is so don't suggest it. He can source HEI parts in South Africa.
