Stroking an engine refers to increasing the swing or "stroke" of the crankshaft. This increases the displacement (size) of the engine and also increases leverage and torque.

The most popular stroker combination these days is to install a 3.75" stroke crank into a 3.48 inch stroke 350 engine. This give you the ever popular "383 stroker" .030 over bore.
