About This Product
The S&S 96-inch Sidewinder kit is a comprehensive big bore stroker package designed for 1984-1999 Evolution engines. This kit features 3-5/8" big bore cylinders finished in a rugged wrinkle black, providing a classic high-performance appearance. By increasing both the bore and the stroke, the Sidewinder kit dramatically increases the engine's displacement and power output. S&S includes precision-matched components to ensure the engine remains balanced and reliable despite the massive increase in performance. This kit is a legendary choice for builders looking to extract maximum power from the Evo platform. Sold as a kit, it provides everything needed to turn a stock engine into a high-performance stroker.
Manufacturer part number: 91-7661.
