– (1) COMP CAM 12-423-8 XTREME ENERGY 224/230 RETRO FIT ROLLER CAMSHAFT – Hydraulic roller profile featuring 276°/282° advertised duration, 224°/230° @ .050 duration and .502″/.510″ lift on a 110° lobe separation. This proven Xtreme Energy grind dramatically improves airflow, torque and engine responsiveness in Chevy 262–400 small blocks.
– 16) HIGH-PERFORMANCE REDLINE RETRO-FIT ROLLER LIFTERS + LINK BAR – Heavy-duty link-bar lifters engineered for stable roller tracking, strong lubrication control and long-term durability with high-lift hydraulic roller profiles like the 12-423-8.
– 1) DOUBLE ROLLER 9 KEYWAY BILLET STEEL TIMING CHAIN KIT (TOR/BRG) – Heat-treated billet steel gears and a dual-roller chain maintain precise cam timing under load. Reduces chain stretch, stabilizes valve events and ensures the aggressive cam lobes operate at maximum performance throughout the RPM range.
– .502″/.510″ LIFT OPENS THE VALVES DEEP INTO THE HIGH-FLOW ZONE – The higher lift allows the cylinder heads to move significantly more air/fuel into the chamber and expel exhaust faster. This results in stronger mid-range torque, faster throttle response and noticeably improved acceleration.

Description
Description
This Competition Cams 12-423-8 hydraulic roller camshaft, Redline Performance link-bar lifter and billet steel double roller timing set package is engineered to significantly improve the performance, sound and responsiveness of Chevy 262–400 small block engines. A step up from mild street cams, the 12-423-8 offers a powerful blend of airflow, torque and drivability.
The camshaft’s .502″/.510″ lift, 224°/230° duration @ .050, 276°/282° advertised duration, and 110° LSA provide the ideal combination of valve lift and valve-open time to dramatically increase cylinder filling. The high-lift lobes open the valves into the cylinder head’s efficient flow zone, while the extended duration keeps them open during peak airflow velocity. This results in stronger mid-range torque, a sharper throttle response and an engine that pulls confidently through the RPM band.
A wider duration split enhances exhaust scavenging and top-end breathing, making this cam perfect for 350, 383 and 400 builds with aftermarket heads, headers and good tuning. The 110° LSA maintains a crisp performance idle while preserving enough vacuum for street use.
The included billet steel double roller timing set ensures precise, consistent timing control—critical for extracting all the power from an aggressive hydraulic roller cam. Hardened gears and a dual-roller chain maintain camshaft accuracy and reduce long-term wear.
Redline Performance link-bar hydraulic roller lifters are matched to the cam’s fast-ramp roller profile, delivering stable tracking and excellent oil control for long-term durability.
This package is ideal for anyone wanting more torque, better throttle response, a stronger exhaust note and improved overall power from their Chevy small block. If you want your engine to feel sharper, pull harder and sound like a true performance build, this cam kit delivers.
