V124 Long Block Engine - Chrome/Wrinkle Black - Big Twin | Custom Chasis w/Alternator-Style Primary
Upgrade your Harley-Davidson powertrain with the S&S Cycle V124 Long Block Engine, part number 310-1159. This high-performance engine is designed for 1984–1999 Evolution Big Twin applications and 1970–1999 custom chassis equipped with an alternator-style primary. Its chrome and wrinkle black finish delivers a distinctive appearance while supporting a durable, performance-focused build.
Specially machined cylinder heads allow the use of a stock-length manifold, helping simplify installation with compatible components. The engine is designed to bolt into stock or aftermarket EFI, carburetor, and air-cleaner configurations. Your existing carburetor may be used with proper re-jetting, while a performance carburetor and performance ignition are required to support the engine’s operating demands.
The S&S Cycle V124 package includes S&S cylinder heads, valve springs, forged rocker arms, a 640 cam, a three-piece flywheel assembly, forged pistons, a high-volume high-pressure oil pump, and electric compression releases. The crank and case are machined for a crank position sensor, providing compatibility with suitable ignition and engine-management systems. Built in the USA, this long block engine is engineered for riders and builders seeking strong performance and dependable components for a custom or replacement Big Twin project.
