Engine Dimensions & Weights

Cummins, Power Stroke, & Duramax Engine Dimensions

The following dimensions are nominal length, width, and height of a fully dressed engine unless otherwise noted. Dimensions of some engines may vary from model year to model year based on changes the manufacturer may have made. 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 an engine swap or diesel conversion.
