COMP CAMS 20-745-9 COMP Cams 20-745-9 Xtreme Energy Hydraulic Roller Camshaft for Small Block Mopar

The COMP Cams 20-745-9 Xtreme Energy camshaft is designed for small block Mopar engines seeking strong street and performance characteristics with the efficiency of a hydraulic roller valvetrain. This camshaft features a .480-inch lift at both the intake and exhaust valves, providing balanced valve movement for responsive acceleration and dependable operation. Its 114-degree lobe separation angle supports a broad, usable powerband and contributes to smooth drivability in properly matched applications.
The camshaft delivers advertised duration figures of 264 degrees on the intake and 270 degrees on the exhaust. With an operating range of approximately 1,000 to 5,000 RPM, the COMP Cams 20-745-9 is suited to street performance combinations that need usable low- and mid-range power rather than a narrow, high-RPM power curve. The hydraulic roller design helps reduce friction compared with conventional flat-tappet configurations while eliminating the need for routine lash adjustments when used with compatible components and correct installation procedures.
This small block Mopar camshaft is supplied as an individual unit and should be selected as part of a complete valvetrain system. For reliable results, verify compatibility with the engine block, cylinder heads, lifters, timing set, valve springs, retainers, pushrods, and rocker components before installation. Always follow COMP Cams installation and break-in recommendations, confirm piston-to-valve clearance, and set the final combination according to the intended vehicle, compression ratio, induction system, exhaust configuration, and transmission. The COMP Cams 20-745-9 combines Xtreme Energy performance characteristics with hydraulic roller convenience for enthusiasts building a practical and responsive small block Mopar engine.
