I didn't see anyone actually answer the question. The calculations are all right (albeit simplified), but the actual question was what does the number mean.

Displacement is a measure of an engine's size. The size is calculated by the volume "displaced" by the piston...the volume in which the piston moves and not the size of the combustion chamber.

The calcuation is the same as finding the volume of a cylinder. It's simply (Radius)2 * (Height) * PI, where the radius is half of the bore and the height is the stroke. Then, just multiply by the number of cylinders.

A stock Chrysler 2.2L engine is 135cid.

A 350cid engine converts to (a large) 5.7L, not 5.6. A 351cid rounds to 5.8L.
