Engine Dimensions & Weights

Cummins, Power Stroke, & Duramax Diesel Engine Dimensions

The dimensions in the tables below represent the nominal length, width, height, and weight of a fully dressed engine unless noted otherwise. Dimensions may vary for some engine models due to model year to model year changes and optional equipment (such as dual alternators). Measuring an engine within an engine bay is not an exact science, but these dimensions will give you a general idea of the required space to perform the engine swap or diesel conversion of your choice. Measurements are listed in inches (in) and weights are listed in pounds (lbs).
