Sleeve length is often overlooked in favor of maximum cubic inches, but in order to build a long-lasting, high-powered engine it is a major consideration. We explore sleeve length, stroke, and selecting rotating assembly components that work in harmony.An engine is an ecosystem of moving, complimentary parts. Changing just one of those parts affects the entire system as a whole. Stroker crankshafts, while the premier way to add power, torque, and displacement, can dramatically change the operating condition of the piston. Without careful attention to detail and proper planning, sometimes for the worse. In this segment, we show you how to ensure your stroker crank works well with the piston and rod combination at hand.
