– COMP CAM 11-445-8 XTREME MARINE 218/224 RETRO FIT ROLLER CAMSHAFT – Hydraulic roller profile with 270°/276° advertised duration, 218°/224° @ .050 and .510″/.510″ lift on a 112° LSA. This Xtreme Energy grind dramatically improves airflow, torque and throttle response in 396–454 big block Chevy engines.
– HIGH-PERFORMANCE REDLINE RETRO-FIT ROLLER LIFTERS + LINK BAR – Heavy-duty link-bar lifters engineered for stable roller tracking, proper oiling and long-term reliability with high-lift hydraulic roller profiles. Built to handle aggressive ramp rates without lifter collapse or wear.
– .510″/.510″ LIFT LETS THE HEADS FLOW AT THEIR FULL POTENTIAL – The high lift position moves each valve deep into the cylinder head’s most efficient airflow zone, allowing more air/fuel charge in and pushing exhaust out more effectively. More airflow = stronger mid-range, cleaner acceleration and a big improvement in how the engine responds.
– 218°/224° @ .050 DURATION FOR AGGRESSIVE BUT STREETABLE PERFORMANCE – Duration specs keep valves open during the peak velocity portion of the intake and exhaust cycle, building extra cylinder pressure and improving combustion efficiency. This produces noticeably stronger torque in the low/mid RPM range — exactly where street cars live.

Description
Description
Upgrade your Chevy 396-454 big-block engine with this performance camshaft and lifter kit featuring the Competition Cams 11-445-8 hydraulic roller camshaft and matched link-bar hydraulic roller lifters. Designed to deliver stronger mid-range torque, noticeable throttle response improvement and enhanced engine character, this combo brings performance gains without stepping into extreme race-only territory.
The camshaft features .510″/.510″ lift, 270°/276° advertised duration, 218°/224° @ .050″ duration and a 112° LSA. Together these specs open up the breathing of your big block: with the increased lift the valves allow more air/fuel mixture to flow in and exhaust to flow out. The 218°/224° @ .050 duration keeps valves open long enough in the efficient airflow window to improve cylinder filling and generate more torque where you use it most. The 112° LSA adds a performance-loopy idle and a strong pull through the mid-range while maintaining street manners.
Included hydraulic roller link-bar lifters provide stable roller motion, reliable oil control and durability suited for the elevated demands of this cam profile. This kit is perfect for classic Chevy big-block muscle cars, trucks and restorations looking for a meaningful performance upgrade: sharper throttle feel, stronger acceleration, louder idle tone and an engine that feels more alive.
If you are looking for real performance gains in a big-block Chevy, better throttle response, improved sound and a cam designed to unlock stronger torque and acceleration — the 11-445-8 camshaft kit is your upgrade.
