You want the holley 20-143 kit. If you don't need the all the parts you can get them a la carte as well. If you don't need it all you're in luck because the kit has been back ordered for months. Ask me how I know.

I put the same engine in my 66 GTO and had the same issues as you are having, I was getting a custom stand alone harness made by Speartech. I still used the GTO ECU which is a E40, I just told Speartech I would be using a f-body alternator and they made my harness with the correct f-body alternator plug.
You can use the f-body alternator in place of the GTO alternator, the f-body alternator is smaller and gives you the needed clearance, it will bolt right in with the existing GTO front bracket, the rear bracket has to be changed to the f-body rear alternator bracket, they are available for around $15-$20on eBay. I sold my GTO alternator and recouped most of the cost of buying the f-body alternator and rear bracket, after all said and done the alternator swap cost me around $40.00

Not sure if this has been gone over yet but does anyone know what the best throttle cable to run with the forward position mounts and a edelbrock or Holley high ram manifold? Should I get a f-body ls1 throttle cable?
