COMP Cams 31-492-9 Xtreme Energy Hydraulic Roller Camshaft Ford Small Block - 212/218 221-302

The COMP Cams 31-492-9 is an Xtreme Energy 212/218 Hydraulic Roller camshaft engineered for Ford small block engines (221-302 c.i., 1963–1995). This camshaft is purpose-built for street and street/strip performance builds where strong throttle response, improved torque, and top-end horsepower are the primary goals.

COMP Cams' Xtreme Energy series bridges the gap between mild street camshafts and all-out race grinds. The aggressive lobe profile delivers better throttle response and top-end power compared to flat-tappet cams of equivalent duration at .050" lift, while maintaining excellent engine vacuum for streetability.

Camshaft Specifications:

• Advertised Duration: 262° Intake / 270° Exhaust
• Duration @ .050" Lift: 212° Intake / 218° Exhaust
• Valve Lift (w/ 1.6:1 Rockers): .519" Intake / .519" Exhaust
• Lobe Separation Angle: 110°
• RPM Range: 1,500–5,500
• Lifter Type: Hydraulic Roller
• Engine Compatibility: Ford 221, 260, 289, 302 c.i. (1963–1995)

Recommended Build Requirements:

• Performance intake manifold and carburetor or EFI
• Headers recommended
• Minimum 9.0:1 compression ratio
• Mild torque converter (stock converter compatible)
• Performance valve springs required — stock valve train components are not recommended with this camshaft's aggressive lobe design

Due to the hydraulic roller lifter design, this camshaft delivers quieter valvetrain operation and reduced maintenance compared to solid roller or flat-tappet alternatives, making it an excellent choice for high-performance street-driven Ford small block builds.
