Small-block pushrod
Windsor
The 289, 302, and 351 Windsor belong to a pushrod V8 tradition. Shared displacement labels can mislead: a 351 Windsor and a 351 Cleveland are different engine families.

WHAT’S UNDER THE HOOD.
Understand the families before comparing the numbers. Displacement is only one part of an engine’s identity.

Cleveland, FE & Boss
First-generation engine choices span several architectures. The Boss 302 combines its own performance design with a small-block foundation; the Boss 429 is a separate specialized engine.

Modular
The 4.6L GT engine arrives for 1996. Two-, three-, and four-valve variants differ in cylinder heads, induction, timing, and service requirements. Later 5.4L and 5.8L performance engines extend the story.

Coyote
The 5.0L Coyote enters the GT for 2011. Later revisions change cylinder heads, fueling, and other hardware. A “5.0” badge alone cannot identify the correct procedure or part.
2016 GT →Specialized 5.2L V8
Voodoo & Predator
The GT350’s naturally aspirated Voodoo and GT500’s supercharged Predator have distinct crankshaft, induction, and transmission contexts. Do not treat equal displacement as interchangeability.
2020 Shelby GT500 →Turbocharged four-cylinder
Lima & EcoBoost
The Fox SVO and S550/S650 EcoBoost share the idea of a turbocharged four-cylinder, not a common engine architecture. Era, engine code, calibration, and supporting hardware remain essential.

Inline-six & V6
Mustang’s six-cylinder history covers multiple unrelated families. The 4.0L SOHC V6 used in early S197 cars is different from the later 3.7L Ti-VCT V6.
