Every mechanic knows just how necessary it is to recognize the exactly firing stimulate of a vehicle or truck engine. Knowing the ideal sequence will assist reduce and even prevent engine vibrations.

The Ford engine is just one of the most used engines in the market, so we’ll emphasis on the Ford Engine Firing bespeak in this article. So, what is the firing stimulate of Ford engines?

The shooting order for the most typical Ford engines, is as follows:

HO Ford 302 engine: 1-3-7-2-6-5-4-8Non-HO Ford 302 engine: 1-5-4-2-6-3-7-8Ford 5.4 engine: 1-3-7-2-6-5-4-8Ford 5.0 liter V8 VIN “N” engine: 1-5-4-2-6-3-7-8 Ford 5.0 liter V8 VIN “P” engine: 1-3-7-2-6-5-4-8Ford 4.6 V8 engine: 1-3-7-2-6-5-4-8Ford 390 engine: 1-5-4-2-6-3-7-8Ford 351 engine: 1-3-7-2-6-5-4-8Ford 351W engine: 1-3-5-7-2-6-5-4-8

When the sequence of the firing of spark plugs or injection of fuel is correct, that will result in a smooth ride for the passengers. Why? There will certainly be a minimum of vibrations within the engine and the whole system. It is how an important it is to obtain the engine firing in the best sequence.

Read on to learn an ext about Ford van engines’ firing orders and the specs for each Ford engine.

Ford Engine shoot Order


There space two varieties of engines – gasoline and also diesel. Gasoline engines usage spark plugs come fire the fuel. Once the air is compressed right into a boiling state in diesel engines, the fuel is injected, and burning occurs.

Moreover, the sequence through which the spark plugs fire (in gasoline engines) and also fuel is injected (in diesel engines) is the engine’s firing order.

Ford engine Co. Has developed different kinds of van engines v differing sizes, capacities, and power capabilities. In fact, there are 7 of these truck engines provided as the motive power for different Ford truck models v the years.

The rest of this article will talk about the shooting orders of these nine various Ford van engines.

Ford Engine Name:Firing Order:
HO 3021-3-7-2-6-5-4-8
Non-HO 3021-5-4-2-6-3-7-8
5.0 V8 VIN “N”1-5-4-2-6-3-7-8
5.0 V8 VIN “P”1-3-7-2-6-5-4-8
4.6 V81-3-7-2-6-5-4-8

Ford 302 shooting Order


The firing order of a Ford 302 engine depends on its version year. More recent HO engines have actually a 1-3-7-2-6-5-4-8 shoot order. Enlarge models have a 1-5-4-2-6-3-7-8 shoot order.

Early 302 engines have the exact same firing orders together the 260 and also the 289 engines, wherein LH = 1-5-4-2-6-3-7-8 and RH = 1-8-7-3-6-2-4-5.

The later on 302 engines (marine) supplied the firing stimulate of 351 W engines, where LH = 1-3-7-2-6-5-4-8 and RH = 1-8-4-5-6-2-7-3. It to be from 1972 come 1974 as soon as they make the switch.

Moreover, the non-HO Ford 302 engine firing bespeak is 1-5-4-2-6-3-7-8. If friend look at the engine’s front, ~ above the passenger side are cylinders 1, 2, 3, and also 4, which room the people close come the firewall.

On the driver side are cylinders 5, 6, 7, and 8, with 8 being close to the firewall. The exact same setup is additionally true through HO 302 engines.


Furthermore, to check if the engine has actually the traditional non-HO firing order, traction the valve cover and put cylinder no. 1 at the height dead facility (TDC). You can do this by manually turning the engine over.

When you feel air coming the end of the hole of spark plug no. 1 through your finger, then it is nearby to the position.

At the point, usage the time marks on the damper to obtain to TDC. Then turn the engine again manually, this time clockwise. Take note of the stimulate the entry valves are opening to check the firing stimulate as offered above. If the verifies the sequence, then you space sure.

If the sequence is different, it yes, really does no matter. Yet write under the order the the intake valves space opening up because that every cylinder. By law this, you will recognize the 302 Ford engine shoot order.

Ford 5.4 shooting Order

Next, let’s look at the Ford 5.4 Triton firing order. That is essential to determine which cylinder height or bank is the primary one to figure out a beginning point. This is also important as soon as you need to readjust the right facet like the ignition coil, petrol injector, or oxygen sensor.


Before noþeles else, you need to examine which cylinder head is number 1. This is the cylinder mind that is put the most forward or the top. The cylinder nearest to the top of the engine is cylinder number one.

The firing stimulate of all Ford 5.4 engines is 1-3-7-2-6-5-4-8. ~ above the passenger side room cylinders 1, 2, 3, and also 4, if on the driver’s side space cylinders 5, 6, 7, and also 8.

Ford 5.0 shooting Order

This is a 5-liter engine. Ford has actually two sport of this engine: the Ford 5.0 liter V-8 VIN “N” engine and the Ford 5.0 liter V-8 VIN “P” engine. So, these two engines have actually their own firing orders.

On the passenger side are cylinders 1, 2, 3, and 4, while on the driver’s side space cylinders 5, 6, 7, and also 8. The distributor rotation is clockwise.

The firing stimulate of the Ford 5.0 liter V-8 VIN “N” engine is 1-5-4-2-6-3-7-8, if the Ford 5.0 liter V-8 VIN “P” engine is 1-3-7-2-6-5-4-8. It does not issue what the positions of the spark plug wires are. So lengthy as this firing order is maintained, there will certainly be no problem.

Thus, if over there is a need to rotate the spark plug lid for every little thing reason, you need not worry about pulling the wires and also rotating them.

Ford 4.6 shoot Order

The shooting order for Ford 4.6 V8 engines is 1-3-7-2-6-5-4-8.With this engines, cylinder number 1 is in ~ the engine’s front and also on the driver’s side. Ford engine Co. Designates the cylinder number in sequential order starting from the front and also the earlier of the engine.

Cylinders 1 come 4 room on the driver’s side, and cylinders 5 to 8 are on the passenger side.

This engine belongs come the modular engine series of Ford engine Co. It has a smaller sized displacement contrasted to the Ford Windsor engines, but it offers much more power. Moreover, with higher power in a smaller sized engine, the modular collection brought come an finish Ford’s Windsor engines.

Ford engine Co. Used the 4.6 engine in assorted vans, cars, and also trucks. The carmaker named this modular engine the Triton. Moreover, Ford industries a DOHC version of this modular engine and also uses the in that Lincoln models. This engine is no longer in production.

This may be because of the significant issues v this modular engine. Among the concerns is regarded the usage of Dupont nylon entry manifolds. They space prone come cracking, and thus, the leaking the coolant.

A second issue involves the challenge in removed the spark plugs and missing threads ~ above the spark plugs.

Ford 390 firing Order

Ford motor Co. Has made 9 adjustments for the 390 V8 engine due to the fact that its start in 1961. In every these 9 variations, Ford maintained the engine’s firing order, i m sorry is 1-5-4-2-6-3-7-8. Ford introduced this engine in answer to the Chevrolet 409 of general Motors.

390 Engine

The 390 of Ford generated much more horsepower 보다 the 409 the GM. Its maximum engine performance created 401 hp. The an initial year it went into production. The was an ext than 41 hp. That the 360 hp. That Chevy 409.

Ford used the 390 engine in building Mercury and also Ford production cars, including several trucks. But because of the bigger dimension of the GM car, car buyers were an ext excited with the Chevy 409.

In fact, Chevy Impalas v 409 engines market from two to three times more than a Ford Galaxie powered by a 390 engine.

However, Ford 390s are still an extremely popular today because of the easy access of the parts. Some auto enthusiasts deserve to push its strength in the 500+ range, particularly if the engine is designed because that racing.

Ford automobile Year Models sharing the Firing bespeak (1-5-4-2-6-3-7-8)

Here room the Ford vehicle year models the share the same firing stimulate of 1-5-4-2-6-3-7-8, starting from the very first model in 1961:

1961 come 1965 – engine through 4 barrel carbohydrate (lower horsepower model) generating 300 hp. V 427 lb.-ft. Of torque.1961, 1963, and also 1965 – v 4 barrel carb (higher hp. Model) producing 330 hp. With 427 lb.-ft. The torque.1961 to 1962 – through 4 barrel carb, generating 375 hp. V 427 lb.-ft. Of torque.1961 come 1962 – with 3 x 2 barrel carbs developing 401 hp. With 430 lb.-ft. That torque.1966 come 1969 – through 2 barrel carbs developing 265 hp. (standard transmission), 275 hp. (automatic transmission) generating 401 lb.-ft. The torque.1966 to 1968 with 4 barrel carb producing 315 hp. With 427 lb.-ft. The torque.1967 come 1968 – through 4 barrel carb generating 320 hp. V 427 lb.-ft. That torque.1966 come 1968 – with 4 barrel carb “GT Model” creating 335 hp. Through 427 lb.-ft. That torque.1969 – through 4 barrel carb generating 320 hp. V 427 lb.-ft. That torque.

Ford 351 shoot Order

Ford 351 engine deserve to either be a 351 (C), a 351 (M), or a 400 M engine. C means Cleveland, and also M stands for Michigan. The shooting orders of these engines room the same. The is 1-3-7-2-6-5-4-8. They are different from the typical 289, 302, and also 351W SBF (Small Block Ford) engines.

These engines have actually cylinder heads through canted valves, similar to the huge Block Chevy engines. Again, the spark plug wires’ place does not issue so lengthy as the firing bespeak is maintained.


Should there be a should rotate the cap, you have the right to pull the wires and rotate castle around. Everything you do, you need to keep the firing order of the engine.

Firing order of Ford 351W Engines

The firing bespeak of Ford 351W engines is 1-3-5-7-2-6-5-4-8. This is different from the bulk of V-8 engines that Ford engine Co. Makes. The carmaker number the engine cylinders beginning at the former left of the engine.

Cylinders 1 through 4 are on the left or passenger side, and cylinders 5 v 8 space on the best or driver’s side. The distributor rotation is counterclockwise.

Importance of correct Firing Order

If the exactly firing order on the Ford 351W is ensured, the ideal spark plugs will fire for the engine to run smoothly. Girlfriend will recognize if the engine is running with the correct firing order if that is to run smoothly and also the plug wires room removed, as what girlfriend will perform if you replace spark plugs.


To ensure that they remain in the correct firing order, brand the wires prior to removing them indigenous the spark plugs. If you occur to rearrange lock the dorn way, you will know how to exactly the arrangement using the wires’ labels.

351 Cubic customs Windsor Engine

Ford engine Co. Introduced the 351 cubic inch Windsor engine in 1969 due to the fact that of the public need for higher power on share engines. At that time, the expense per gallon of petrol was cheap. The engines at that time produce an ext than 300 horsepower.

Ford offered the 351 Windsor as the stock engine for a selection of vehicles for several years. However, the carmaker diminished its engines’ power as soon as emission standards were introduced, causing even the powerful Mustang to be limited to 169 hp.
