SBC Hyd. Roller Camshaft Fastburn.

The Chevrolet Performance SBC Hydraulic Roller Camshaft Fastburn (Part #24502586) is a high-performance hydraulic roller cam engineered for small-block Chevrolet LT-series engines from 1992–1997. This is an aggressive street-strip camshaft designed to maximize mid-range and top-end horsepower while maintaining the reliability and street manners that hydraulic roller technology provides. The Fastburn profile delivers broad power characteristics that suit both dyno testing and real-world highway performance.

Specifications define this cam's character: 0.492-inch lift on both intake and exhaust, 218-degree intake duration and 228-degree exhaust duration (at 0.050-inch tappet rise), and a 112-degree lobe separation angle. The RPM range spans 1800–5800, anchoring power delivery across the usable rev window for street and strip applications. Hydraulic roller design eliminates the valvetrain complexity of mechanical rollers while providing the reduced friction and durability of roller contact, a proven combination in small-block applications where reliability matters. The Fastburn profile is calibrated for vacuum signal characteristics typical of carbureted and early fuel-injected small-block platforms.

This camshaft addresses builders targeting bolt-on performance from factory or lightly modified small-block architecture. Typical installations include street rods, classic Corvettes, and early Camaro platforms where OEM-style hydraulic lifter compatibility is essential. The moderate lift and duration avoid the need for custom valve reliefs or pushrod geometry modifications, allowing installation in stock or mildly ported cylinder heads. The 1800 RPM idle point keeps low-speed manners streetable, while the 5800 RPM power band ceiling suits naturally aspirated applications.

Hydraulic roller cams occupy a middle ground in the performance spectrum—less aggressive than mechanical roller designs, more capable than flat-tappet profiles. Chevrolet Performance's Fastburn grind has earned a following among small-block restomod builders who prioritize balanced power without the complexity of running a separate cam control system. Each unit ships ready for installation in a standard LT-series block.
