T143 Long Block Engine

The T143 Long Block Engine is a high-performance engine designed for Harley-Davidson motorcycles. It features S&S B3 cylinder heads CNC-machined with two-bolt exhaust flanges, ensuring a robust and efficient exhaust system.

Equipped with S&S 635 easy-start gear drive cams and 1.725:1 rocker arms, this engine provides a total lift of .674", enhancing performance and responsiveness. The S&S Super Stock™ T2 crankcases come with a reed breather valve and three-piece flywheels, ensuring durability and optimal performance.

This engine also includes an S&S high-flow oil pump and cam cover, as well as premium high-performance tappets, delivering superior lubrication and reliability.

Made in the USA, the T143 Long Block Engine fits in stock chassis without the need for cutting or frame modifications. Please note that a T143-specific or custom exhaust is required, and carb/intake or ignition systems must be purchased separately. The revised oil routing on '99-'06 Touring models eliminates the need for an oil line installation kit.
