The definitive, photo-driven guide to mastering the Harley-Davidson Twin Cam engine.

This technical shop manual from Wolfgang Publications explains the complete "how and why" of high-performance Twin Cam engine building. Packed with over 500 crisp color photos, this is not a product catalog-it is a true, hands-on workshop manual. Each chapter focuses on a specific subassembly, allowing garage mechanics and builders to jump straight to the technical breakdowns they need, exactly when they need them.

For anyone planning to build or rebuild a Twin Cam motor that balances reliable street power with long-term durability, author Timothy Remus walks you through two complete assemblies from start to finish.

Expert Technical Breakdowns Include: The Camchest: Camshaft installation, timing setup, and component fitment.
The Bottom End: Detailed flywheel assembly, truing, and precision balancing.
Cylinder Heads: Professional valve work and performance porting insights.
Top-End Assemblies: Step-by-step big-bore top-end jobs performed directly in the chassis, plus a complete 124ci bench build.

Take full advantage of the elite skills and insider knowledge shared by the master builders at R&R Cycles-creators of everything from hot street engines to record-setting competition motors at Bonneville. Whether you want to tackle simple garage maintenance or a complete ground-up motor build, the clear specifications and step-by-step photo sequences you need are right here.
