The 153-cubic-inch (2.5 L) 153 was an inline-four engine which was designed for use in the entry-level Chevy II/Nova. It is a four-cylinder version of the Chevrolet 230 inline-six. Usage of the 153 lasted until 1970 when the inline-six was made the base powerplant with the Chevy II/Nova. Currently, descendants of the 153 are used with industrial (forklifts or generators) or marine applications.

The 153 has a bore of 3.875 inches (98.4 mm) and a stroke of 3.25 inches (82.6 mm). The firing order is 1-3-4-2. A later variant of the 153, the 181, used a larger 4-inch (101.6 mm) bore and a longer 3.6-inch (91.4 mm) stroke. The 181 (branded by GM as the Vortec 3000 for marine or industrial usage) was never installed in passenger cars. The 153 engine is entirely different from the later Pontiac 151-cubic-inch (2.5 L) Iron Duke, but the two are often confused today. In South Africa, smaller displacement versions of this engine were also built. The larger one has a displacement of 2,319 cc (2.3 L; 141.5 cu in), and a stroke of 3 in (76.2 mm) with the same bore.[1] There was also a narrow-bore 1,960 cc (2.0 L; 119.6 cu in) engine which has a bore of 3 916 in (90.5 mm).[2] This is also the bore used for Chevrolet's closely related "194" six-cylinder engine.
