A stroker motor is an engine that utilizes a different crank to achieve more displacement with the same engine block. An engine fitted with an altered crankshaft that has a larger stroke increases the engine's size without increasing the size of the block. Here are some normal stroker motors and their stock and aftermarket strokes.

Motor stock stroke  Stroke & CID

 305     3.48        3.75 = 334

 350     3.48        3.75 = 383

                       3.875 = 395

                          4.0 = 408 

 400     3.75      3.875 = 420

                          4.0 = 434

 454      4.0        4.25 = 496

                          4.5 = 525

 All sizes are from a .030 bore on the 305 and 350 and .060 on the big blocks
