NW Task Force · 03-11-2013, 11:57 PM

Hey folks.......... my 57' used to have coil/points distributor with a 235 straight six. The wiring is all "Painless Wiring" and has been since buying it from the previous owner. The little 235 ran good with the painless kit and one wire alternator. Fast forward............. now I have installed a V8 with HEI distributor. What exactly do I need to wire up to the HEI and from where? The old coil wires are marked and I am not sure if these are to be used in wiring up the HEI? Anyone have a good way to wire up the HEI from a coil/points style distributor (diagrams, pics, etc)? Thanks!
