If you have an 8-cylinder, and Pertronix/Ignitor (i.e. model 1), and your coil's primary resistance is minimum 1.5 ohms, then you don't need the ballast resistor as the text says.
i tried an ignitor II on my 69 440. would not crank. followed instructions. explain bypass on ballast please see if i can learn anything. i bought a used unit and it may be bad
