Ford 5.4L Triton Engine
The Ford 5.4L Triton is a 330 cubic inch V8 from Ford's Modular family, built from 1997 to 2014 for the F-150, F-250, Expedition, Navigator and E-Series vans. Output ranges from roughly 230 to 550 horsepower depending on model year and valve configuration. A tested used 5.4L runs $1,247 to $2,550. A remanufactured long block runs $3,380 to $6,665.

Used vs Remanufactured 5.4L Triton
| Tested used | Remanufactured | |
| Price | $1,247 – $2,550 | $3,380 – $6,665 |
| Lead time | 3–5 days prep + 2–4 days transit | Often 2–4 weeks |
| Cam phasers | Cold-start run tested before shipping | New |
| Spark plugs | Your installer changes them either way | New |
| Warranty | 6 months, parts + return freight | Typically 12 months |
| Mileage | Documented from the donor odometer | Reset to zero |
When remanufactured makes more sense
- You plan to keep the truck 8+ years and want the longest possible warranty
- Your budget allows the extra $1,500–$4,000
- You can wait several weeks
When tested used is the better buy
- Your truck is off the road now and you need it running this week
- The vehicle's total value doesn't justify a $4,000+ engine
- You want documented real mileage rather than a rebuild you can't inspect
- Your installer will change plugs and inspect the timing set during the swap anyway
The cam phaser argument, addressed directly. Phaser rattle is a real 3V issue, but it is a diagnosable one. It is loudest on a cold start. Every 3V unit we ship is cold-started and run tested before it leaves the yard, and we tell you what we heard. That test is what turns a $1,500 gamble into an informed purchase.

The Three Versions: 2V, 3V and 4V
Ordering the wrong version is the single most common mistake on a 5.4L purchase.
2-Valve (1997–2003) — Two valves per cylinder, single overhead cam. Roughly 235–260 hp. Simplest, cheapest, easiest to work on.
3-Valve (2004–2010) — Three valves per cylinder plus variable cam timing. Around 300 hp. More power, but introduced the cam phaser and two-piece spark plug issues.
4-Valve (supercharged / specialty) — DOHC, four valves per cylinder. SVT Lightning, Harley-Davidson F-150, Ford GT. Low volume, expensive, not interchangeable with standard truck engines.
2V and 3V are not interchangeable. Different heads, intake manifolds, wiring and ECU calibration.
How to Tell Which 5.4L You Have
Read the 8th digit of your VIN.
| 8th VIN digit | Engine |
| L | 5.4L 2V SOHC, gasoline |
| 5 | 5.4L 3V SOHC, gasoline |
| V | 5.4L 3V SOHC, flex fuel (E85) |
| Z | 5.4L bi-fuel / CNG (fleet) |
| 3 | 5.4L supercharged (Lightning, Harley-Davidson) |

Spark Plugs — the question people ask most
1997–2003 (2V) — plugs eject from the head
The aluminum head holds the plug with only about four threads. Under pressure they can strip out and blow free. You'll hear a sudden loud exhaust-like noise and lose a cylinder.
Fix: a thread insert repair (Time-Sert or similar). Does not require replacing the head. Ford revised the head design partway through 2003.
Buying note: ask whether any cylinder already has an insert. A properly installed one is fine.
2004–2008 (3V) — plugs break on removal
The 3V used a two-piece spark plug. Carbon builds up around the lower electrode shell, and the plug snaps on removal, leaving the shell stuck in the head.
Fix: a dedicated extractor tool (Lisle 65600 or equivalent). Most experienced Ford shops have one.
5.4L 3V plug part numbers and specs
| Item | Spec |
| Original plug (2004–2008 3V) | Motorcraft SP-515 |
| Current replacement | Motorcraft SP-546 / SP546X — supersedes SP-515 |
| Gap | 0.045" |
| Torque | 30–38 Nm (22–28 ft-lb) |
| Socket | Dedicated 9/16" spark plug socket required |
| Cost | Around $22 per plug, roughly $180 for a set of eight |
Note on part numbers: SP-515 was designed for the larger 5.4L 3-valve truck head. Do not substitute SP-462 or SP-514 — those are 4.6L 3-valve Mustang plugs and are a different size. Ford moved to an updated plug design for later trucks, so confirm the correct part number against your exact year and VIN before ordering.
Important: this is a maintenance item, not an engine defect. It does not mean the engine is bad. Budget extra labor time for the plug change, and change them while the engine is out — access is far easier.
Cam Phaser Rattle — 3V, 2004 to 2010
The variable cam timing phasers wear and rattle, loudest on a cold start, often paired with a worn timing chain tensioner. It sounds like a diesel or a loose chain slapping.
Fix: phaser and tensioner replacement. Some owners fit a phaser lockout kit, though that removes the variable timing benefit.
What we do about it: every 3V unit is cold-started and run tested before shipping, and we report what we heard. This is the specific check that makes a used 3V a safe buy instead of a gamble.
Firing Order and Cylinder Layout
5.4L V8 firing order
1 - 3 - 7 - 2 - 6 - 5 - 4 - 8
This is the same for both the 2-valve and 3-valve 5.4L. The cylinder head design differs between them, but the combustion sequence does not.
Cylinder layout
Stand in front of the truck, looking at the engine.
| Bank | Side | Cylinders |
| Bank 1 | Passenger side | 1, 2, 3, 4 |
| Bank 2 | Driver side | 5, 6, 7, 8 |
Cylinders run front to back: 1–4 on the passenger side, 5–8 on the driver side. Cylinder 1 is closest to the front bumper on the passenger side.
The common mistake: Ford numbers cylinders sequentially within each bank, while some other manufacturers alternate side to side. Mixing up Bank 1 and Bank 2 is the single most frequent error when diagnosing misfire codes on a 5.4L.

| Ford Excursion | 2000–2005 | 2V |
| Ford E-150 / E-250 / E-350 | 1997–2014 | 2V / 3V |
| Lincoln Mark LT | 2006–2008 | 3V |
| Ford SVT Lightning | 1999–2004 | Supercharged 4V |
Van applications ran the 2V well past 2004 — always verify by VIN, not by year.
Which Years to Buy
- Late 2003 (2V) — revised heads, most of the plug ejection risk resolved. Best budget option.
- 2009–2010 (3V) — the most refined of the 3V run. Revised plug design and phaser hardware.
- 1997–2002 (2V) — cheapest, but highest plug ejection risk. Check for prior repairs.
- 2004–2008 (3V) — expect the plug removal job and possible phaser work. Price accordingly.

Frequently Asked Questions
Where can I find a reliable Ford 5.4 Triton engine for sale?
Tested used 5.4L Triton engines run $1,247 to $2,550 and ship in 3 to 5 days. Remanufactured long blocks run $3,380 to $6,665 and often take two to four weeks. Used is the better choice when you need the truck running soon or when the vehicle's value doesn't justify a $4,000 engine. Ask for the cold-start run test result before you buy — that is what confirms cam phaser condition on a 3V unit.
Should I buy a used or remanufactured 5.4 Triton?
Remanufactured makes sense if you're keeping the truck long term and can wait several weeks for a 12-month warranty. Tested used makes sense if you need the truck this week, want documented real mileage, and your installer is changing plugs and inspecting the timing set during the swap anyway. The price gap is $1,500 to $4,000.
How much horsepower does a Ford 5.4 have?
The 5.4L V8 produces between 230 and 550 horsepower. Output depends on model year and valve configuration. The 2-valve makes roughly 235 to 260 hp, the 3-valve around 300 hp, and supercharged 4-valve variants in the Lightning and Ford GT reach the top of that range.
What is the firing order on a Ford 5.4 Triton?
The firing order is 1-3-7-2-6-5-4-8, and it is the same for both the 2-valve and 3-valve versions. Cylinders 1 through 4 are on the passenger side (Bank 1) and 5 through 8 on the driver side (Bank 2), running front to back. Ford numbers cylinders sequentially within each bank rather than alternating side to side, which is the most common source of confusion.
What spark plugs does a 5.4 Triton 3V need?
The original plug for the 2004 to 2008 5.4L 3-valve is the Motorcraft SP-515, now superseded by the SP-546 and SP546X. Factory gap is 0.045 inches and torque is 30 to 38 Nm, or 22 to 28 ft-lb, using a dedicated 9/16 inch spark plug socket. Plugs run around $22 each, so roughly $180 for a set of eight. Confirm the part number against your exact year and VIN before ordering.
Why are 5.4 Triton spark plugs so hard to change?
On 2004 to 2008 3-valve engines the plug is a two-piece design. Carbon builds up around the lower electrode shell, and the plug snaps on removal, leaving the shell in the head. On 1997 to 2003 2-valve engines the opposite happens — only about four threads hold the plug, so it can eject from the head under pressure. Both are known, fixable issues rather than engine failures.
Will a 3-valve 5.4L fit my 2-valve truck?
No. The 2V and 3V use different cylinder heads, intake manifolds, wiring harnesses and engine control calibration. Check your 8th VIN digit: L means 2V, 5 or V means 3V. We verify this before anything ships.
How many miles is too many for a used 5.4 Triton?
Under 120,000 miles is a strong buy. 120,000 to 180,000 is acceptable on a compression-tested unit with documented service history. Above 200,000 we'd recommend a lower-mileage unit. Every listing shows actual mileage read from the donor odometer, not an estimate.
