It gradually replaced the Windsor small-block and 385 big-block engines over several years in the mid-1990s. The engine is modular in that it can be adapted to V8 or V10 with a variety of 2-valve and multivalve heads. It is used in Ford trucks (called the Triton or Intech) and cars (called the Duratec). Ford recently introduced a 3-valve SOHC Variable Cam Timing system on this engine.

The engines were first produced in Romeo, Michigan; additional capacity was added in Windsor, Ontario.

[edit]

4.6

The first in the family was the 4.6 L (281 in³) SOHC V8 introduced in the 1991 Lincoln Town Car. It was designed at the same time as the General Motors Premium V, best-known as the Cadillac Northstar engine, but released 6 months earlier.

Over the years, the 4.6 came in 2-valve, 4-valve, and 3-valve versions (single-, double-, and single-overhead cam respectively). It has also came with both iron and aluminum blocks. Bore and stroke are roughly square at 3.552" (90.2mm) in and 3.543" (90mm) in respectively.

Until 1999, all car engines were produced at the Romeo plant. In 1999 and 2000, Mustang's engines were produced in Windsor. Production was moved back to Romeo in 2001. All truck engines are from the Windsor plant. All aluminum blocked engines were produced at Romeo. While the basic design remains the same the two plants had different designs for main bearings, heads (cam caps), valve covers (number of bolts) and crankshaft (number of flywheel bolts).

The Modular DOHC was on the Ward's 10 Best Engines list for 1996, while the SOHC was on the list for 2005.

2-valve

Vehicles using the cast iron 16-valve SOHC 4.6 include the following:

[edit]

Cracking manifold

The 2-valve engine was originally equipped with a nylon-composite intake manifold which was found to crack at the front crossover, leaking coolant and possibly causing engine failure. A class-action suit was filed on behalf of owners, resulting in a settlement announced on December 17, 2005.

The following vehicles were included in this class-action suit settlement:

4-valve

The aluminum 4-valve DOHC version was introduced in the 1993 Lincoln Mark VIII. It also featured a variable length intake manifold. The engine was revised for 1999 with better cylinder heads, hotter cams, and an improved intake manifold.

Vehicles using the aluminum 32-valve DOHC 4.6 include the following:

[edit]

3-valve

Image:2006 Ford Mustang GT engine.jpg A 3-valve SOHC head with variable timing was introduced in 2005. It is similar to the Triton used in the Ford F-Series. Block material varies between the aluminum block used in the 2005+ Ford Mustang and the iron block used in the 2006+ Ford Explorer, though aluminum heads are used in both applications.

The 3-valve SOHC engine was on the Ward's 10 Best Engines list for 2006.

Vehicles using the 3-valve SOHC version include:

  • 2005+ Ford Mustang, 300 hp (224 kW) and 320 ft·lbf (434 N·m)
  • 2006+ Ford Explorer, 292 hp (218 kW) and 300 ft·lbf (407 N·m)

5.4

See also Ford Triton engine

A 5.4 L SOHC version is used in Ford Trucks and SUVs and called the Triton. The Triton was on the Ward's 10 Best Engines list for 1997 and 1998 and again for 2000 through 2002. A supercharged version powers the Ford F-150 Lightning in 2-valve configuration. The 5.4L 4-valve version also made an appearance in the limited production Cobra R in 2000 and the Ford GT, the upcoming 2007 Shelby Mustang GT500.

The Ford GT uses a highly-specialized version of the Modular engine. It is an all-aluminum dry-sump version with a Lysholm screw-type supercharger for better top-end. The Shelby GT500 uses a much more ordinary engine, a 4-cam 32-valve version of the iron-block Triton with an Eaton R122 Roots-type blower and air-to-liquid intercooler.

5.4 engines are also used in Australian Falcons, with minor changes. The 5.4 3 valve SOHC is used in Falcons, Fairmonts, Fairlanes and LTDs. The higher performance XR8 and GT models have the 4 valve DOHC models, at 260 kW (348 hp) and 290 kW (388 hp) respectively. These engines are known as Boss 260 and Boss 290, however they have nothing in common with the Boss engines fitted to the 1960s/70s Mustangs.

Applications:

[edit]

6.8

The 6.8 L V10 is another in the modular family. It was created by adding a pair of cylinders to the center of the 5.4 L V8. It uses a balance shaft to smooth the vibrations present due to the added cylinders. Output was 265 hp and 405  ft·lbff. The Ford V10 was used in 1997-2002 Ford Trucks as the Triton V10.

Cammer racing engine

In 2005, Ford Racing Performance Parts introduced a 5.0 L crate engine for use in motor racing and home-made performance cars, officially called M-6007-T50EA, but more widely known as "Cammer". Because the latest Mustang has only 3-valve heads, FRPP developed the Cammer from the previous generation's DOHC 32-valve engine. The engine received further modifications in the harness, electronic engine managenement, magnesium intake manifolds, an alloy/aluminum block, race-prepped cylinder heads and camshafts and increased compression ratio, but the biggest difference is a 3.700" bore (3.552" is stock for modulars) achieved by resleeving the block.

The 5.0 L Cammer is used mainly in Mustang racing cars in the Grand-Am Cup and the SCCA World Challenge's GT class, but can be installed in a variety of other applications, including road cars, dragsters and sports car racing prototypes.

Ford of Australia

Ford of Australia uses modular V8s in the Ford Falcon and Ford Fairlane sedan model ranges, as well as in its high performance FPV division models. The current Triton V8s are named Boss by Ford of Australia, with a number designation referring to power output in kW. The 230kw engine and Boss 260 and 290 shortblocks, heads and crankshafts are built in Windsor, Ontario. The Boss motors offer Cobra R heads and locally sourced parts including intake and pistons. All are built with cast-iron blocks. The name Barra refers to the model designation of the cars these engines were originally fitted to. Specifically it's called the BA Falcon (BA = Barra as a nickname, hinting at the Barracuda fish). The model previous to this was the AU Falcon, also fitted with the 230kw mod motor.

Ford of Australia 'Triton' Engines:

  • 230kw 3-valve SOHC 5.4 L V8. 230 kW (310 hp/313 PS) @ 5350 rpm, 500 N·m (368  ft·lbff) at 3500 rpm
  • Boss 260 4-valve DOHC 5.4 L V8. 260 kW (349 hp/354 PS) @ 5250 rpm, 500 N·m (368  ft·lbff) at 4000 rpm
  • Boss 290 4-valve DOHC 5.4 L V8. 290 kW (388 hp/394 PS) @ 5500 rpm, 520 N·m (383  ft·lbff) at 4500 rpm
