Ford FE V8 Firing Order Diagram: 352 360 390 406 427 428 Cylinder Numbering

This document is a firing order reference diagram for Ford FE-series V8 engines, specifically the 352, 360, 390, 406, 427, and 428 cubic-inch displacements. It states the firing order as 1-5-4-2-6-3-7-8. A cylinder numbering illustration shows the engine block from above with the front of the block at the bottom: cylinders 1 through 4 are on one bank (numbered 1 at the front to 4 at the rear on the left side of the drawing) and cylinders 5 through 8 on the other bank (5 at the front to 8 at the rear). A distributor cap illustration is included, and the diagram notes that the rotor under the cap spins counter-clockwise. This reference allows a mechanic to correctly route spark plug wires from the distributor cap to each cylinder, verify cylinder identification when performing tune-ups or diagnostics, and confirm proper rotor rotation direction when installing or timing the distributor on any of the listed Ford FE big-block V8 engines.
