Haynes manual figure showing cylinder numbering, distributor location, and firing orders for inline-six and V8 engines.
This scanned manual page (attributed to a Haynes manual for 1973-79 Ford Broncos per the watermark) shows engine firing order and distributor information. For six-cylinder in-line engines, the firing order is 1-5-3-6-2-4. For V8 engines, it provides a cylinder numbering diagram showing cylinders 1-4 on one bank and 5-8 on the other, with the distributor located at the front of the engine. Two distributor cap diagrams illustrate the firing order and rotation, which is counterclockwise for both. For the 302, 360, 390, and 460 engines, the firing order is 1-5-4-2-6-3-7-8. For the 351/400 engines, the firing order is 1-3-7-2-6-5-4-8. The diagrams show the exact spark plug wire positions on each distributor cap, allowing a reader to correctly route ignition wires from the distributor to each cylinder. A 'Front' arrow orients each diagram relative to the vehicle. This page is useful for anyone performing a tune-up, replacing spark plug wires, or reinstalling a distributor on these Ford engines.
