Ford Motor Company’s 5.4-liter or 330-cubic-inch V-8 engine debuted in 1997 with two valves per cylinder for its truck line. The automaker launched the second version for its truck line with four valves per cylinder in 1999. A third version of the 5.4-liter V-8 with three valves per cylinder arrived in 2002, first for passenger cars and then for trucks. high performance vehicles and Lincoln. Browser. These engines were Ford’s first V-8s to displace 5.4 liters.


The 5.4-liter V-8 belongs to Ford’s modular engine family that also includes the 4.6-liter V-8 and the 6.8-liter V-10. The first modular engine used a simple camshaft. “Modular” is derived from the modular tooling system in Ford manufacturing plants to quickly adapt to different types of production and due to the interchangeable components of the three engines. The original version of the 5.4-liter V-8 earned a spot in Ward’s Auto World’s “Top 10” engines. An estimated 1.3 million V-8 modular engines were built in 2001 alone. The basic architecture of the three versions remains identical with the number of valves and other performance components that change to suit the needs of each model. Ford replaced the 5.4 V-8 in 2010 with the 6.2-liter, 411-horsepower V-8, although the 2011 Ford Shelby GT500 still used the 5.4 four-valve V-8.

2-V 5.4

Ford installed its first 16-valve 5.4L V-8 in the 1997 Ford F-150 pickup and marketed it as a Triton V-8. It featured a 3.55-inch bore and a 4.16-inch stroke. The longer stroke increased the engine platform height over the 4.6-liter version. It featured a cast iron block, aluminum heads, and a multi-port electronic fuel injection system. The valve lifters were of a hydraulic lash adjuster design with a roller follower. Other features included a forged steel crankshaft and fracture-split powder metal connecting rods. A 9-to-1 compression ratio helped it develop 255 horsepower and 350 pound-feet of torque. Some versions developed up to 260 horsepower, while the high-performance Ford SVT Lightning F-150 came with a supercharger and a power rating of 380.

4-V 5.4

Ford sold the 5.4-liter 32-valve as an InTech V-8. It was a new version of the original 5.4 two valve with double overhead camshaft. Ford favored the InTech in its trucks, performance cars, the Lincoln Navigator and the Ford Falcon in Australia. But the 5.4L 32-valve that powered the SVT Cobra high-performance cars differed significantly from the truck versions. It came with high-flow cylinder heads, a higher lift cam, and a 9.6-to-1 compression ratio to develop 385 horsepower and 385 pound-feet of torque. The Shelby GT500’s 5.4 featured a Roots-type supercharger with an air-to-liquid intercooler to generate up to 550 horsepower and 500 pound-feet of torque. In contrast, the Lincoln Navigator’s 5.4 produced 300 horsepower and 355 pound-feet of torque.

3-V 5.4

Ford introduced the 24-valve version in 2002 to power sedans, but two years later offered it on F-Series trucks. It featured variable camshaft timing and more power and torque than two-valve models. The 5.4L 24-valve provided less friction than the two-valve, single-cam versions with roller follower. The cylinder heads were made of aluminum alloy. It delivered 300 horsepower and 365 pound-feet of torque, in part due to a 9.8-to-1 compression ratio. Eventually, production rose to 320 horsepower.
