Comp Cam 12-432-8 Xtreme Energy 230/236 Retro Fit Roller Camshaft with Premium Link Bar Roller Lifters | LIFT: .510"/.520" | FITS: Chevrolet SBC 5.7L 350 265 327 400 | Strong Torque

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.

• THIS IS A COMP CAM & REDLINE PERFORMANCE CAM KIT ASSEMBLED BY OUR EXPERT ENGINEERS TO CREATE THE HIGHEST QUALITY CAMSHAFT KIT AT AN AFFORDABLE PRICE. EVERY PART IN THIS KIT HAS A HIGH-PERFORMANCE SPEC RATING AND IS GUARANTEED TO BE OF THE HIGHEST OF QUALITY AND PERFORMANCE.
• (1) COMP CAM 12-432-8 XTREME ENERGY 230/236 RETRO FIT ROLLER CAMSHAFT - Xtreme Energy hydraulic roller grind with 282°/288° advertised duration, 230°/236° @ .050 and .510"/.520" lift on a 110° LSA. Built to wake up Chevy 262–400 small block street machines with stronger torque and sharper throttle response.
• 16) HIGH-PERFORMANCE REDLINE RETRO-FIT ROLLER LIFTERS + LINK BAR - Heavy-duty link-bar lifters engineered for stable roller tracking, strong oil control and long-term durability with high-lift, fast-ramp hydraulic roller profiles. A proper match for the Xtreme Energy lobe design.
• .510"/.520" HIGH LIFT FOR BIG AIRFLOW GAINS – The aggressive lift moves the valves deep into the head’s high-flow region, allowing more intake charge and better exhaust scavenging. That extra airflow translates directly into stronger mid-range pull, harder acceleration and more top-end horsepower.
• 230°/236° @ .050 DURATION FOR REAL STREET/STRIP POWER – Longer duration keeps valves open during the most efficient airflow window, building cylinder pressure where you actually drive. You get stronger low- and mid-range torque, quicker RPM climb and a noticeably more responsive engine from about 2,200–5,800 RPM.
• 110° LSA FOR CRISP IDLE AND STRONG MID-RANGE – The 110° lobe separation sharpens mid-range torque and adds a mildly rough performance idle without killing vacuum. Perfect balance of sound, drivability and power for street cars that still see regular use.
• STRONGER TORQUE, HARDER ACCELERATION & BETTER SOUND – This cam and lifter combo gives your SBC a more aggressive exhaust note, sharper throttle reaction and a stronger pull through the RPM range—exactly what street/strip Chevy owners are looking for.
• DESIGNED FOR SERIOUS STREET SMALL BLOCKS – Excels in Chevy 305, 327, 350, 383 and 400 combos with intake, headers, 2500+ stall converter and gear. Ideal for Camaros, Novas, Chevelles, C10s and hot rods that need more power and attitude than a mild cam can deliver.
