V124 Long Block Engine - Chrome/Natural - Big Twin | Custom Chasis w/Alternator-Style Primary
Upgrade your Harley-Davidson Big Twin with the S&S Cycle V124 Long Block Engine, part number 310-1160. 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. Carburetor re-jetting is required for proper performance and tuning.
The engine is designed to bolt into stock or aftermarket EFI, carburetor, or air cleaner configurations, giving builders flexibility when completing a custom powertrain setup. The crank and case are machined for a crank position sensor, and the assembly includes S&S cylinder heads, S&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.
Additional 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&S performance foundation for a compatible Big Twin project. Installation requires a performance ignition and performance carburetor, along with appropriate tuning and supporting components. Verify chassis, primary, fuel system, ignition, and accessory compatibility before installation.
