Ford V8 Distributor Cap & Cylinder Numbering Diagram - #1 Plug Wire Position
Schematic diagram showing the cylinder numbering layout of a V8 engine with cylinders 1 through 8 arranged in two banks.
This scanned schematic, titled by its uploader as 'DizzySet.jpg', is a distributor setup/firing-order reference diagram for a V8 engine. It shows a top-down view of an eight-cylinder engine block with two banks of cylinders: cylinders 4, 3, 2, 1 on one bank and 8, 7, 6, 5 on the other. Superimposed at the front cylinder (cylinder 1) is a circular distributor cap illustration with its eight terminal positions numbered around the circumference. The number 1 terminal is highlighted in pink with a diamond marker, indicating the position of the number-one spark plug wire on the cap, and an arrow at the lower right suggests rotor rotation direction or an alignment reference. A reader can learn the cylinder numbering convention for the engine and how the spark plug wires are ordered around the distributor cap relative to the highlighted #1 terminal. The document contains no written text, part numbers, year statements, or engine displacement callouts — it is purely a numeric pictorial reference. Companion files in the same album (firing orders, distributor specs, ignition system specs) suggest it accompanies a broader ignition tune-up reference set for a 1972 Ford, likely a 351 Cleveland-family engine based on album context.
