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

Remove the factory resistor as it isn't needed or wanted with the HEI. That wire looks a bit light to use with an HEI though a most of us run at least a ten gage wire to the HEI,

The wire that was running from the neg post on the coil should be for the tach. If you have a tach you will need to change ends on it and run it to the tach pin on the dist cap next to the bat pin. The tach will probably be off though as it was set for a six cylinder. You can usually remove the cup and set the tach to 8 cylinder pretty easily. Most have a 4-6-8 switch on the back side of the tach it's self inside the cup. if it doesn't have a tach just remove that wire.

If the ign wire is hot when the engine is cranking you can just extend it
