This performance-focused engine is designed for 1984–1999 Evolution Big Twin models and 1970–1999 custom chassis applications using an alternator-style primary. Specially machined cylinder heads allow the use of a stock-length manifold, helping simplify installation while supporting compatibility with your existing carburetor.

The crank and case are machined for a crank position sensor, and the assembly includes S\u0026amp;S cylinder heads, S\u0026amp;S valve springs, forged rocker arms, a 640 cam, and a three-piece flywheel assembly. A high-volume, high-pressure oil pump supports dependable lubrication for performance-oriented applications.\u003cbr\u003eAdditional components include electric compression releases and forged pistons for enhanced durability and easier starting operation. The engine is manufactured in the USA and is intended for riders and builders seeking a complete S\u0026amp;S performance foundation for a compatible Big Twin project.
