This Competition Cams 12-432-8 Xtreme Energy hydraulic roller camshaft and Redline Performance link-bar lifter kit is built to transform how a Chevy small block 262–400 engine runs, sounds and responds. Designed as a retro-fit hydraulic roller profile for non-roller SBC blocks, it delivers serious street performance while remaining usable for real-world driving. The 12-432-8 cam features .510"/.520" lift, 282°/288° advertised duration, 230°/236° duration @ .050, and a 110° LSA. The higher lift opens the valves deep into the cylinder head's high-velocity flow zone, significantly improving intake and exhaust flow. The extended duration at .050 keeps the valves open during peak airflow, building stronger cylinder pressure and producing a harder mid-range hit and stronger acceleration. The 110° lobe separation angle sharpens mid-range torque and creates a mildly rough performance idle that clearly says “built motor” without making the car unmanageable. With the right supporting parts—intake, headers, 2500+ stall converter and gear—this cam pulls hard from about 2,200 RPM to 5,800 RPM, making it ideal for aggressive street builds and weekend strip use. Redline Performance link-bar hydraulic roller lifters are included to complement the cam's aggressive ramp rates. These lifters maintain stable roller contact, improve oil control and provide the durability required for high-lift, performance use, giving you a matched valvetrain package that works together. For Chevy small block owners who want real gains in torque, throttle response, sound and top-end power—without stepping into a race-only profile—this Competition Cams 12-432-8 cam and Redline link-bar lifter kit is an outstanding choice.
