Ford Small Block Stroker Engine Build Torsional Vibrations

As the crank rotates and receives forces from the firing pulses, it advances and retards from its true nondeflected position. This is called a torsional vibration and must be adequately damped as it will lead to an early crank breakage. Additionally, such torsionals also upset the cam dynamics leading to spurious valve bounce.
