V80 Long-Block Engine - Natural - Custom Chassis | Evolution Big Twin

The S&S CYCLE V80 Long-Block Engine is a reliable, stock-height replacement designed specifically for 1984-1999 Evolution Big Twin motorcycles and custom chassis builds from 1970 to 1990 with an alternator-style primary. This engine features specially machined cylinder heads that allow the use of stock-length manifolds, ensuring compatibility with your existing exhaust system. Crafted in the USA, it provides a straightforward upgrade path for aging engines, delivering improved performance and durability. The package includes S&S performance cylinder heads, a standard oil pump, flat top cast pistons, S&S 585 valve springs, forged rocker arms, and a 508 camshaft, all engineered to enhance your motorcycle's power output and reliability. The engine's design facilitates easy installation as a direct bolt-in replacement, simplifying the upgrade process. Fuel and ignition systems are not included; users should use their existing carburetor, noting that rejetting is required for optimal performance. Additionally, this engine is EFI compatible, though calibration with an aftermarket module or tuner is necessary to fully utilize fuel injection benefits. Whether restoring a vintage bike or building a custom chopper, the S&S V80 Long-Block offers a high-quality, American-made solution for enthusiasts seeking to boost their motorcycle’s performance and longevity.
