Understand power ratings on snow blowers what does CC vs Torque Vs Horsepower mean?

CC (cubic centimeters) is the measure of volume inside the cylinder when the piston is at bottom dead center. The ratio of the diameter of the cylinder to the stroke of the piston influences the torque and horsepower ratings of an engine. Typically when an engine has a stroke that is larger than the diameter of the cylinder it would generate a higher ratio of torque to horsepower. The shorter stroke engines typically rev higher and develop higher horsepower to torque ratiOS.
