This manual page, titled "Cylinder Numbers and Firing Order," shows cylinder numbering and firing orders for Ford V8 engines. Two diagrams are presented, each depicting a top view of the engine with the left cylinder bank numbered 4-3-2-1 (front to rear) and the right bank numbered 8-7-6-5 (front to rear). Each diagram also includes a distributor cap illustration labeled "Cylinder location and distributor rotation" showing the plug wire terminal positions and counterclockwise distributor rotation. The upper diagram applies to the 351W, 351C, and 302 HO engines, which use firing order 1-3-7-2-6-5-4-8. The lower diagram applies to "All others" (other Ford V8s covered by this manual), which use firing order 1-5-4-2-6-3-7-8. A reader can learn which firing order applies to their engine, how the cylinders are physically numbered on each bank, and where each spark plug wire connects on the distributor cap relative to distributor rotation. The page was uploaded to a 1972 Ford Ranchero gallery alongside other Cleveland/Windsor engine reference documents.
