I'm not 100% sold on fuel injection for my HO build. A carb will simplify things and alow me to removed alot of wiring and sensors from the car. What I'm wanting to know is how much can you take out wiring and sensors wise before the stock ignition stops working? I guessing the ECU controls the ignition. Can I leave all the stock ignition in place, gut all the sensors and stuff then put a MSD 6 system in it? I know I can use a vacuum advance distributor but I do not want that. I also know I can just set the timming and leave it there, but I do not want that ether.
