Call for availability
4-year no-fault nationwide warranty — includedOn gas engines in non-commercial use, at no extra charge. The builder’s standard cover is 3 years, parts only. Every gas engine we sell includes the 4-year no-fault warranty with labour, at no extra charge.
- “No fault” means we do not investigate why it failed — if a covered engine fails inside the term, it is covered.
- Labour is paid up to CAD $95.00 per hour — a cap on the rate, not a flat payout — and only for the remove-and-replace hours in the Mitchell labour guide. Diagnostic time is covered up to 2 hours, and fluids up to CAD $200.00. Towing and a rental car are not covered. Anything not listed here needs to be agreed with us before the work starts.
- The 4 years start the day the engine is installed, and a claim needs proof that a professional shop installed it.
- Unlimited kilometres, and no deductible.
- Call us before any warranty work starts, so we can authorise it. Labour paid on a repair we were not asked about first is not covered.
- A claim starts with a call to us. We file it with the manufacturer, and the manufacturer pays it.
Diesel engines, and engines put into commercial service, are not covered by this 4-year warranty — the terms vary by engine, so call us for the terms on the unit you’re pricing.
Add an install kit. Thermostat, water pump, belts, hoses, filters, plugs and leads — the parts that should not go back on a new engine. Ask for one with this engine and we quote it on the same order. What a proper install replaces

Ford Modular 4.6L / 5.4L V8
Also known as: Triton (truck versions), InTech (Lincoln DOHC versions), Mod motor, 4.6 Modular, 5.4 Triton
Overview & history
Ford's Modular V8 story starts with the 1991 Lincoln Town Car, carrying the new 4.6L SOHC V8 — Ford's first clean-sheet V8 in decades and the start of a $4 billion program to replace its pushrod engines. The 'Modular' name never referred to interchangeable parts; it described the flexible tooling at the Romeo Engine Plant in Michigan and the Windsor and Essex plants in Ontario. The Crown Victoria and Grand Marquis picked up the 4.6 in 1992, the Mustang GT in 1996, and the F-150 in 1997 — the same year the taller-deck 5.4L arrived to replace the 351 Windsor in trucks, wearing the Triton badge. Over the next two decades the family stretched from taxi and police fleets to the supercharged Ford GT supercar and Shelby GT500, and variants earned Ward's 10 Best Engines honours in multiple years. The last 4.6 was built in May 2014 for the E-Series van, and 5.4s soldiered on in E-Series chassis even later — one reason 4.6/5.4 cores are so common in the remanufacturing world.
Specs & engineering
- •Overhead-cam architecture throughout — SOHC 2-valve and 3-valve, DOHC 4-valve — a clean break from Ford's pushrod V8s
- •Deep-skirt block with cross-bolted main caps; cast iron in most applications, aluminum in DOHC Mark VIII, Mustang Cobra, and Ford GT versions
- •Aluminum heads on every variant; the 1999 'PI' (Performance Improved) head and intake redesign gave 2-valve engines a real power bump
- •Shared 90.2 mm bore — the 4.6 runs a 90.0 mm stroke, the 5.4 a 105.8 mm stroke in a taller-deck block
- •Fracture-split powder-metal connecting rods across the family
- •3-valve engines (2004+) added variable cam timing and charge-motion intake plates
- •Romeo (car) and Windsor (truck) builds differ — jackscrew main caps and an 'R' mark vs dowelled caps and a 'W'/diamond mark — and many small parts don't interchange
- •The 6.8L V10 shares the architecture, and the 5.0L Coyote that replaced the family is a direct descendant
Generations & variants
- •4.6L 2V SOHC (1991-2014) — the fleet workhorse: Town Car, Crown Victoria, Grand Marquis, Mustang GT 1996-2004, F-150, E-Series
- •4.6L 4V DOHC 'InTech' (1993-2004) — Lincoln Mark VIII and Mustang Cobra, ending with the supercharged 390 hp 'Terminator' Cobra of 2003-04
- •4.6L 3V SOHC (2005-2010) — Mustang GT, Explorer, and F-150 with variable cam timing
- •5.4L 2V SOHC Triton (1997 into the mid-2010s) — F-150, Super Duty, Expedition, and E-Series vans
- •5.4L 3V SOHC (2004-2014) — F-150 2004-2010, Expedition and Navigator 2005-2014
- •5.4L 4V DOHC — Navigator InTech (1999-2004), 2000 Cobra R, then supercharged in the Ford GT (2005-06) and Shelby GT500 (2007-12)

Casting numbers
| F65E-BB | Windsor-plant 4.6L SOHC iron block, 1996-1999 truck/van engines (not interchangeable with the Romeo F65E-CC) |
| F65E-CC | Romeo-plant 4.6L SOHC block — same era as the Windsor F65E-BB but a different casting with different main-cap hardware |
| F75E | Windsor SOHC block and NPI head castings used through 1999; Windsor heads use individual cam caps and 12 cam-cover bolts |
| F6AE / F7AE / F7ZE / F8ZE | Romeo 2V NPI (non-Performance-Improved) heads, 1996-1999, with oval intake ports |
| XL3E | 2V PI (Performance Improved) head, 1999-2001, square intake ports and heart-shaped chambers — fits both 4.6L and 5.4L |
| 2L1E | Later PI-style 2V head casting commonly paired with XL3E in 4.6L/5.4L reman applications |
Known issues & fixes
Spark plug blow-out (1997-2003 2V engines, especially 5.4 trucks)
What to watch for: A sudden loud pop, then a misfire and hissing from one coil well — these heads hold the plug with only about four threads
The fix: A thread-insert repair (TimeSert/BigSert style) done in the vehicle is a proven permanent fix; later head castings carry more threads.
Spark plugs seizing and snapping on removal (2004-2008 3V engines)
What to watch for: Original two-piece Motorcraft plugs carbon-lock, and the shell stays behind when you pull the plug
The fix: Remove warm after a penetrating-oil soak, keep an extractor handy for broken shells, and install one-piece redesigned plugs.
Cam phaser and timing chain wear (4.6L/5.4L 3V)
What to watch for: Diesel-like knock or rattle at warm idle plus VCT codes; low oil pressure or overdue oil is usually the root cause
The fix: Replace phasers, chains, guides, and tensioners as a set, ideally with a high-volume oil pump — piecemeal phaser swaps on a worn chain don't last.
Plastic intake manifold cracking (1996-2001 4.6 2V cars)
What to watch for: Coolant smell or seepage at the front coolant crossover, often dripping near the alternator
The fix: Install the updated manifold with the aluminum crossover — the standard fix for two decades.
Did you know?
- ★The 'Modular' name has nothing to do with swapping parts — it referred to flexible plant tooling that could switch between engine variants in days.
- ★A modified 806 hp Modular-based V8 powered the Koenigsegg CCR to 241 mph in 2005, briefly the world's fastest production car.
- ★The Ford GT supercar's 550 hp engine shares its basic 5.4L architecture with the engine in a work van.
- ★Crown Victoria Police Interceptors and taxis routinely saw 500,000 km on their 4.6s — fleets kept ordering them until the last car in 2011.
