The 4.6L & 5.4L V-8 engines are part of Ford's Modular overhead camshaft engine family, as is the 6.8L V-10 optional in 3/4 & 1 ton Ford trucks through 2010. The 4.6L & 5.4L become optional V-8 powerplants in the Ford F-150 for the 1997 model year. The term "Modular" refers to the ability of the engine production facility to rapidly change its tooling to produce different versions of the engine, and does not refer to the fact that the engines share many components. Though the architecture of the 4.6L & 5.4L is very similar, the 5.4L features a longer stroke and therefore requires a taller deck height than that of the 4.6L. The 5.4L utilizes a small bore, long stroke design, while the 4.6L utilizes a nearly square design (approx. 1:1 bore to stroke ratio). The engines have earned an overwhelming reputation of reliability and become a popular engine amongst long term Ford F-150 owners. Both engines have been featured on Ward's 10 Best Engines List on multiple occasions, and received a variety of honorable mentions from various industry analysts. The "Triton V-8" title has been used to label the modular engines in Ford F-150s since 1997.Torque Specifications for Ford 5.4L-330ci-V8
