4.6
The smallest Triton was the 4.6 L (4605 cc/281 in³) V8, based on the 90° Ford Modular engine design. Bore of the iron block is 3.55 in and stroke is 3.54 in. This engine is available with either a cast iron or aluminum block, but both use aluminum heads. Thus far, all 4.6 L Tritons have been SOHC 2-valves per cylinder designs. Power is 231 hp and torque is 293 ft.lbf. It is likely that a 3-valve version will also be produced.
Ford's Romeo #2 plant in Romeo, Michigan produces five different 4.6 L modular V8s, of which two are Tritons. The two Triton lines are the cast iron unit used in the Ford F-Series, Expedition, and Econoline and the aluminum block version used in the Lincoln Aviator, Ford Explorer, and Mercury Mountaineer.
The cast iron block version produces 232 hp (173 kW) at 4750 rpm and 291 ft.lbf (394 Nm) of torque at 3450 rpm. The aluminum version produces 302 hp (225 kW) at 5750 rpm and 300 ft.lbf (407 Nm) of torque at 3250 rpm. Both use SFI fuel injection, roller rockers, fracture-split forged powder metal connecting rods, and an assembled reinforced plastic intake manifold.
Vehicles using this engine include:
- Aluminum block
- 2003-present Lincoln Aviator
- 2003-present Ford Explorer
- 2003-present Mercury Mountaineer
- Cast iron block
- 2003-present Ford F-150/F-250
- 2003 Ford Expedition
- 2003 Ford Econoline
5.4
Another Triton based on the Ford Modular engine design was the 5.4 L (330 in³) iron/aluminum V8. Bore is the same as the 4.6, but stroke is lengthened to 4.17 in. The 5.4 L Triton family is available in three different versions:
2-valve Triton
The basic 5.4 L Triton is built in Windsor, Ontario at Ford's Windsor #2 plant. As of 2004, it was used in most Ford trucks. Output is 260 hp (194 kW) at 4500 rpm with 350 ft.lbf (474 Nm) of torque at 2500 rpm. It has an cast iron engine block and aluminum SOHC 2-valve cylinder heads. It uses SFI fuel injection, roller rockers, fracture-split forged powder metal connecting rods, and an assembled reinforced plastic intake manifold.
Vehicles using the 2-valve Triton engine include:
- 2000-present Ford Excursion SUV
- 1998 Lincoln Navigator SUV
- 2003 Ford F-150
- 2003 Ford Excursion
- 2003 Ford Expedition
- 2003 Ford F-Series Super Duty
- 2003 Ford Econoline
4-valve InTech
Lincoln introduced the InTech version of the 5.4 L modular engine in 1999. It features DOHC heads with 4 valves per cylinder.
This engine uses a cast iron engine block and aluminum cylinder heads. It is built in Romeo, Michigan at the Romeo #2 plant. It uses SFI fuel injection, has roller rockers, and features fracture-split forged powder metal connecting rods and an assembled reinforced plastic intake manifold.
Output is 300 hp (224 kW) at 5000 rpm with 355 ft.lbf (481 Nm) of torque at 2750 rpm.
Vehicles using the 4-valve Intech engine include:
- 1999-2004 Lincoln Navigator SUV
- 2002 Lincoln Blackwood pickup truck
3-valve
In 2004, Ford introduced a new 3-valve SOHC head, improving torque. This engine also includes continuously-variable intake valve timing, and first appeared in Australian Ford models [1] (http://waw.wardsauto.com/ar/auto_fords_power_trip). The engine is built at Ford's Essex, Ontario plant. The engine is not generally referred to with either the InTech or Triton name.
It has an cast iron engine block and aluminum cylinder heads. It uses SFI fuel injection, has roller finger followers, and features fracture-split forged powder metal connecting rods. The intake manifold is assembled of reinforced plastic.
Output is 300 hp (224 kW) at 5000 RPM with 365 ft.lbf (495 Nm) of torque at 3750 RPM.
Vehicles using the 3-valve engine include:
- 2003 Ford Barra
- 2004-present Ford F-150
- 2006-present Lincoln Mark LT
- 2003-2005 Lincoln Navigator
6.8
Ford built a V10 variant for use in large trucks. It displaces 6.8 L (6802 cc/415 in³) and bore and stroke are 90.2 mm and 105.7 mm, the same as the 5.4 L V8. Both 2-valve and 3-valve versions are produced.
2-valve V10
The 2-valve version, built at Ford's Windsor, Ontario #2, was the first. Introduced in 1997, it has an cast iron engine block and aluminum SOHC 2-valve cylinder heads. It uses SFI fuel injection, roller followers, fracture-split forged powder metal connecting rods, and a assembled reinforced plastic intake manifold. Output in 2003 was 310 hp (231 kW) at 4250 rpm with 425 ft.lbf (576 Nm) of torque at 3250 rpm.
Applications:
- 2000-2005 Ford Excursion SUV
- 1997-2001 Ford F-Series pickup truck
- 1997-2001 Ford E-Series van
3-valve V10
For 2005, Ford introduced a 3-valve version of the 6.8 L V10. This is built at Ford's Essex, Ontario plant along with the other 3-valve Modular engines. Output is up to 355 hp (265 kW) and 455 ft.lbf (617 Nm).
Vehicles using this engine include:
- 2005 Ford F-Series Super Duty
