Info on Ford's Modular Engine AKA the Triton
 

The 5.4 L (5408 cc, 330 CID) V8 is a member of the Modular engine family first introduced in the redesigned 1997 Ford F-150 as a Triton V8.

Bore diameter is 90.2 mm (3.552 in) and stroke is 105.8 mm (4.165 in), the increased stroke necessitated a taller 256 mm (10.079 in) engine block deck height. A 169.1 mm (6.658 in) connecting rod length is used to achieve a 1.60:1 rod to stroke ratio.

The 5.4 L 2V was built at the Windsor Engine Plant, while the 5.4 L 3V moved production to the Essex Engine Plant beginning in 2003. The SVT 5.4 L 4-valve engines are built at Romeo Engine Plant, hand assembled on the niche line.
2-valve

Introduced in 1997, the SOHC 2-valve 5.4 L has a cast iron engine block and aluminum cylinder heads. The 5.4 L features multi-port fuel injection, roller finger followers, fracture-split powder metal connecting rods, and in some applications a forged steel crankshaft.

The 2-valve SOHC 5.4 L engine was on the Ward's 10 Best Engines list for 1997–1998 and 2000–2002.

Vehicles equipped with the 16-valve SOHC 5.4 L include the following:

3-valve

In 2003, Ford introduced a new 3-valve SOHC cylinder head with variable camshaft timing (VCT), improving power and torque over the previous 2-valve SOHC version.

The 3-valve cylinder head was first used on the 2003 Ford Fairmont 5.4 L Barra 220 engine in Australia. The 3-valve 5.4 L was introduced to the North American market in the redesigned 2004 Ford F-150.

Vehicles equipped with the 24-valve SOHC VCT 5.4 L include the following:

2003–2005 Ford Fairmont, 3-valve SOHC, 295 hp (220 kW) and 347 lb·ft (470 N·m)

4-valve


In 1999, Ford introduced the DOHC 4-valve 5.4 L in the Lincoln Navigator under the InTech moniker, making it the second engine to use this name.

Ford later used versions of the DOHC 4-valve 5.4 L in the 2000 Ford Mustang SVT Cobra R, the Ford GT supercar, and the Ford Shelby GT500. The DOHC 4-valve 5.4 L is also used in the Ford Falcon line in Australia under the Boss moniker.

The SVT Cobra R version of the 5.4 L 4-valve V8 had several key differences from its Lincoln counterpart. While the iron block and forged steel crankshaft were sourced directly from the InTech 5.4 L, the Cobra R powerplant benefited from new, high-flow cylinder heads that were designed with features developed for Ford's "Rough Rider" off-road racing program, application specific camshafts with higher lift and more duration than other Modular cams, forged I-beam connecting rods sourced from Carillo, forged pistons that provided a 9.6:1 compression ratio, and a unique high-flow "cross-ram" style aluminum intake manifold. The Cobra R was rated at 385 hp (287 kW) and 385 lb·ft (522 N·m) though chassis dynamometer results have shown these ratings to be conservative with unmodified Cobra Rs often producing nearly 380 hp (280 kW) at the rear wheels.

The Ford GT version of the 5.4 L is a highly-specialized version of the Modular engine. It is an all-aluminum, dry-sump 5.4 L 4-valve DOHC with a Lysholm screw-type supercharger and showcases numerous technological features, such as dual fuel injectors per cylinder and oil squirters for the piston skirts, not found in other Ford Modular engines. The GT 5.4 L benefits from an improved version of the high-flow 2000 Cobra R cylinder head and unique high-lift camshafts. The GT is rated at 550 hp (410 kW) and 500 ft·lbf (678 N·m), though independent tests conducted on chassis dynamometers have shown these numbers to be conservative, with as delivered Ford GTs often producing nearly 550 hp (410 kW) at the rear wheels.

The Shelby GT500 uses a 4-valve DOHC 5.4 L with an Eaton M122H Roots type supercharger and air-to-liquid intercooler. The GT500 5.4 L shares its high-flow cylinder head castings with the Ford GT, with only minor machining differences, and shares camshafts with the 2003–2004 Ford Mustang SVT Cobra; which have less lift and duration than the Ford GT camshafts. The 2007-2010 GT500 engine used an iron engine block, while the 2011 GT500 5.4 L receives a new aluminum engine block, with Ford's first production application of their patented Plasma Transferred Wire Arc (PTWA) cylinder coating, eliminating the need for pressed in cylinder liners. The PTWA spray apparatus was co-developed by Ford and Flamespray Industries of Long Island, New York, for which they received the 2009 IPO National Inventors of the Year Award. The 2011 GT500 engine weighs 102 lbs. less than the previous iron-block version, thanks in part to the lack of cast iron cylinder liners.

All of the 5.4 L 4-valve engines destined for use in SVT vehicles, such as the Ford GT and Shelby GT500, have been hand-built by technicians at Ford's Romeo, Michigan plant.

Vehicles equipped with the 32-valve DOHC 5.4 L include the following:

6.8 L V10

The 6.8 L (6760 cc, 413 CID) V10 is another variation of the Modular family created for use in large trucks. Bore size is 90.2 mm (3.552 in) and stroke is 105.8 mm (4.165 in), identical to the 5.4 L V8. Both 2-valve and 3-valve versions are currently produced, though they are soon to be phased out in favor of the new 6.2 L "Boss" V8. The 6.8 L uses a split-pin crank with 72° firing intervals and a balance shaft to quell vibrations inherent to a 90° bank angle V10 engine. The engine's firing order is 1-6-5-10-2-7-3-8-4-9.

The 2-valve version, built at Ford's Windsor, Ontario LVL engine line, was first introduced in 1997. For 2005, Ford introduced a 3-valve non-VCT version of the 6.8 L V10 . The 3-valve engine is built alongside the 2-valve engine at Ford's Windsor, Ontario engine plant.
