The Chevrolet S10 Variable Timing Sprocket allows the cam and crank to remain in perfect synchronization while providing the tuner with an easy way to move valve events for more power. At its highly basic, the Variable Timing Sprocket is a substitution of a plain gear with a multi-keyway or bushing-equipped wheel, allowing builders to shift cam timing a few degrees in either direction without replacing the entire chain set. Properly clocked, this Variable Timing Sprocket makes the factory timing marks match up exactly without the two or three degree errors that can cost an engine scores of horsepower. Advancing the cam through the Variable Timing Sprocket opens intake valves earlier, increasing low end torque which is applied by the S10 pickup for daily hauling duty. Conversely, retarding the cam ensures that the valves remain open longer when the S10 is operating at high rpm, allowing performance-minded drivers to push the S10 into the upper reaches of its power band with confidence. Early Chevrolet editions were based on a single keyway design that required precise factory machining. Later Chevrolet models adopted the adjustable Variable Timing Sprocket, providing owners with a built-in degree wheel alternative that makes fine tuning easier during rebuilds.
