Ford 289 Firing Order and Distributor Diagram
Ford 289 Firing Order and Distributor Diagram with 1-5-4-2-6-3-7-8, physical numbering, identification cautions and routing procedure.
The 289 Small-Block V8 firing order is 1-5-4-2-6-3-7-8. Passenger-side cylinders are 1-2-3-4 and driver-side cylinders are 5-6-7-8, with both banks numbered front to rear.
The 289 Small-Block V8 firing order is 1-5-4-2-6-3-7-8. Passenger-side cylinders are 1-2-3-4 and driver-side cylinders are 5-6-7-8, with both banks numbered front to rear. A firing order is the sequence in which the cylinders begin their power strokes. It is not the same thing as cylinder numbering, distributor-cap clock position, or ignition-coil connector order. Confusing those references can create a no-start, violent backfire, dead cylinders, or a diagnostic trail that looks like a fuel or mechanical problem.
Use the verified order only after identifying the engine family and camshaft. Classic engines can accept camshaft swaps that change the required sequence, while modern coil-on-plug engines have no distributor cap to route. The table, bank diagram, and procedure below keep those concepts separate and show how to confirm No. 1 on compression before moving any wires.

Select each cylinder to walk through the firing order. Cylinder-bank numbering and distributor direction must match the identified engine family.
Ford 289 Firing Order

|---|---|---|
| Firing order | 1-5-4-2-6-3-7-8 | Confirm exact engine |
| Physical numbering | Passenger-side cylinders are 1-2-3-4 and driver-side cylinders are 5-6-7-8, with both banks numbered front to rear. | Orient by the timing/front end |
Many rebuilt 289s receive a 351W/5.0 HO-pattern cam with the alternate 1-3-7-2-6-5-4-8 order. Confirm the camshaft when history is unknown, and locate the number 1 tower from compression TDC before routing the cap counterclockwise.
Which 289 Small-Block V8 firing order applies?
Covers original-pattern Ford 289 small-block camshafts and distributor ignition; the camshaft, not the block casting alone, ultimately determines the firing order. This distinction matters because the engine can look nearly identical from above. Treat the camshaft or engine assembly as the authority when parts have been mixed. A firing order cast into an intake, copied from a generic decal, or remembered from another V8 is not enough to identify a modified engine.
The application table separates the order, cylinder banks, and ignition-system notes. Read all columns before routing. The first number in 1-5-4-2-6-3-7-8 is cylinder 1, but the physical No. 1 terminal can appear in different clock positions when a distributor has been installed on a different gear tooth.
