Ford 302 V8 Firing Order Diagram: Standard vs. 5.0 HO
Ford 302 firing order guide covering early 1-5-4-2-6-3-7-8 and 5.0 HO 1-3-7-2-6-5-4-8 orders, cylinder numbering, and distributor routing.
A standard early Ford 289/302 commonly uses 1-5-4-2-6-3-7-8. The 1982-and-later 5.0 HO and 302 engines using a 351W-order cam use 1-3-7-2-6-5-4-8. Confirm the installed camshaft before routing wires.
A standard early Ford 289/302 commonly uses 1-5-4-2-6-3-7-8. The 1982-and-later 5.0 HO and 302 engines using a 351W-order cam use 1-3-7-2-6-5-4-8. Confirm the installed camshaft before routing wires. 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 302 V8 Firing Order Diagram
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| Early/standard 289–302 | 1-5-4-2-6-3-7-8 | Common non-HO cam order |
| 1982+ 5.0 HO / 351W-order cam | 1-3-7-2-6-5-4-8 | Verify camshaft |
| Passenger bank | 1-2-3-4 | Front to rear |
| Driver bank | 5-6-7-8 | Front to rear |
Ford Performance explicitly documents both orders. The distributor turns counterclockwise when viewed from above on the traditional small-block Ford.
Which 302 / 5.0L firing order applies?
Ford used two legitimate orders: the standard 289/302 order and the 351W-style order used by the 5.0 HO and matching camshafts. 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.
Bank numbering and verification on the 302 / 5.0L
Ford small-block cylinders 1–4 are on the passenger side and 5–8 on the driver side, both front to rear.
Ford Performance explicitly documents both orders. The distributor turns counterclockwise when viewed from above on the traditional small-block Ford.
Ford 302 / 5.0L specifications can change by model year, engine, platform, wheel, and installed component. Confirm the VIN or engine identity, part numbers, fastener condition, and the current manufacturer instructions before service.
Procedures used with this specification
These steps are the same for every vehicle in this family, so they are documented once rather than repeated on each page. The values above remain specific to this Ford 302 / 5.0L.
