351C SOLID ROLLER CAM XR280R 242/248°@50 .657/664″ 110°

Description

Unlock superior engine efficiency and power output with the 351 C Solid Roller Cam XR280 R, engineered to optimize valve timing and lift for enhanced combustion. This camshaft addresses the need for precise valve control and durability in demanding performance applications.

The cam features a 242/248° duration at 0.050″ lift, which increases the time valves remain open, allowing greater air-fuel mixture intake and exhaust flow. This translates directly into improved horsepower and torque across the power band, enhancing acceleration and engine responsiveness.

Its valve lift of 0.657″ on the intake and 0.664″ on the exhaust ensures maximum valve opening for efficient cylinder filling and scavenging. The 110° lobe separation angle balances power delivery and idle quality, enabling a stable yet aggressive engine character suitable for performance-driven setups.

Constructed by Comp Cams, this solid roller camshaft weighs 3.98 kg, providing a robust component that maintains precise timing with minimal flex under high RPM conditions. Its dimensions—61.50 cm long, 6.60 cm wide, and 8.00 cm high—ensure compatibility with 351 Cleveland engines and similar configurations requiring a compact yet high-performance camshaft.

The solid roller design reduces friction and wear compared to flat tappet cams, extending engine life and reducing maintenance intervals. It also supports higher RPM ranges, making it ideal for racing applications or high-performance street engines where durability and consistency are critical.

Integrating this camshaft into your engine build means enhanced power delivery through optimized valve events, improved throttle response, and reliable operation under strenuous conditions. Its well-defined specifications provide a precise fit and performance upgrade tailored to the 351 Cleveland platform.

Choose the 351 C Solid Roller Cam XR280 R from Comp Cams to achieve targeted performance improvements with proven durability and engineered precision. This camshaft stands as a definitive upgrade for enthusiasts seeking measurable gains in power and engine longevity.
