Ford V8 & 6-Cylinder Firing Order Diagrams - 351/400 V8, Other V8, Inline Six
Ford firing-order and distributor cap wiring diagrams for V8 (351/400 and others) and 6-cylinder engines.
This document is a scanned schematic page showing spark plug wire routing and firing orders for three Ford engine families. The top-left diagram covers all V8 engines except the 351 and 400 V8, showing a firing order of 1-5-4-2-6-3-7-8 with the distributor cap terminal layout, clip locations, and wire routing from the cap to cylinders 1-4 on one bank and 5-8 on the other. The top-right diagram covers the 351 and 400 V8 engines, with a firing order of 1-3-7-2-6-5-4-8 and its corresponding cap layout and clip positions. The bottom diagram covers all 6-cylinder (inline six) engines, showing firing order 1-5-3-6-2-4, the wire routing from the distributor to cylinders 1 through 6 along the engine, and a detail view of the distributor cap terminal numbering with clip locations. Each diagram includes the fan/engine front orientation so the reader can identify cylinder numbering and correctly route plug wires. A reader can learn the correct firing order for their engine type, which distributor cap tower connects to which cylinder, and where the cap retaining clips are located. No years, part numbers, or wire colors are stated in the document itself.
