💡 Key Insights
- Camshaft Choice is Critical: The video dives deep into cam selection, explaining why a moderate-duration cam with optimized lift and lobe separation actually provided better real-world power.

This isn’t just paper horsepower—it’s usable, reliable power that any restoration project would be proud to have under the hood.
- Mahle Motorsport Internals: Forged pistons, rods, and rings from Mahle ensure this classic car engine rebuild can handle serious abuse without sacrificing longevity. The builder highlights how modern materials and design techniques let you push vintage LS platforms further than ever before.
- Supporting Mods Matter: The team didn’t skimp on supporting hardware—long-tube headers, a free-flowing intake, and a custom tune all contribute to the final result. The takeaway? Balanced performance upgrades are essential for unlocking your engine’s true potential.
