The term “Dodge 5.2” is shorthand for 5.2-liter Dodge engines. These eight-cylinder engines have been used by Dodge—a company under the Chrysler brand—since the mid-1980s. The 5.2 is equipped in many pickup trucks, though it has appeared in vans and even sedans. While specifications may vary per specific year and model, most of the 5.2-liter engines’ baseline specs remain consistent.
Dodge’s 5.2-liter engine features a V-type eight-cylinder construction with a 318-cubic inch displacement. The 5.2-liter 318 CID is a lightweight, single cam engine with hydraulic roller tappets. Its cylinder blocks and cylinder heads are made of cast-iron, and its camshaft is made of nodular cast-iron. The engine’s bore is 3.91 inches with a 3.31-inch stroke, and its compression ratio is 9.1: 1 with a throttle body bore of 50 millimeters.
