Spark plugs

Why does my distributor cap have nine spark plugs coming out of the top of it? On a 1983 f150 5.8L 4X4

The center post is where the HT current goes into the distributor from the coil & contacts the rotor.
The rotor 'rotates' & delivers power, in turn, to the 8 plug terminals......which is why the wires have to be in the correct position in the cap, matching the engine firing order.

Translation from Aussie engineer-speak: HT = High Tension, meaning high voltage.

Sorry! As I was pulling this up after seeing the e-mailed notice that you had posted I realized my mistake - long before the page came up. Bummer! I knew better. Won't happen again.
