You need some punctuation in that huge sentence, otherwise it can be read at least three different ways. I did figure out the engine only runs when the ignition switch is in the "crank" position. That is characteristic of an open ignition ballast resistor. It is bypassed during engine cranking to make up for the lower battery voltage. Chrysler does that with the ignition switch.

Don't scrap that old 440. They're getting hard to find and are real popular.
