If you divide stroke by bore, you get a numerical value for the stroke/bore ratio. Many production passenger car engines have a stroke/bore ratio between 0.8 to 1.1. Truck stroke/bore ratios are typically higher (1.0 to 1.4) to improve efficiency and low speed torque. The higher the stroke/bore ratio, the less RPM the engine can safely handle, but the more low end torque it will produce.
