Introducing the COMP Cams 2224S/2251S SB Chevy Roller Camshaft from Crane Cams, a high-performance camshaft solution designed specifically for small-block Chevy engines. This camshaft is part of COMP Cams' race-proven XE276 series, which delivers exceptional power gains while maintaining excellent driveability and reliability.
The 2224S/2251S SB Chevy Roller Camshaft features a unique grind design, with a 2224 duration at 0.050-inch lift for the intake and a 2251 duration at 0.050-inch lift for the exhaust. The intake lobe centerline is located at 112 degrees of crankshaft rotation, while the exhaust lobe centerline is set at 110 degrees. This grind provides an optimal lift curve for enhanced power production throughout the RPM range.
One of the standout features of this camshaft is its roller tip technology, which is employed on both the intake and exhaust lobes. The roller tips reduce friction and promote smooth valve operation compared to traditional flat-tappet camshafts. This results in improved engine efficiency, reduced wear, and an overall increase in power output.
Additionally, the 2224S/2251S SB Chevy Roller Camshaft is compatible with a wide range of small-block Chevy engines. It is suitable for engines with hydraulic roller lifters and a stock or mildly modified valvetrain. For those seeking even more performance, the camshaft can also be used in conjunction with high-performance valve springs and solid lifters.
Crane Cams' manufacturing process involves using state-of-the-art CNC machining and induction hardening techniques to produce a precision-made camshaft that delivers consistent power gains and long-lasting performance. The 2224S/2251S SB Chevy Roller Camshaft is backed by Crane Cams' industry-leading customer support and a 1-year limited warranty against manufacturing defects.
In summary, the COMP Cams 2224S/2251S SB Chevy Roller Camshaft from Crane Cams offers a high-performance solution for small-block Chevy engines, delivering increased power output, improved engine efficiency, and reduced wear thanks to its roller tip technology and optimized grind design. This camshaft is suitable for a wide range of applications and is backed by Crane Cams' unwavering commitment to quality and customer support.
