Product Description

The COMP Cams 84-131-6 Magnum Solid Camshaft is a performance upgrade designed specifically for the Nissan/Datsun L-Series inline 6-cylinder engine family (L24, L26, L28) found in the iconic 240Z, 260Z, 280Z, and 280ZX sports cars as well as various Datsun trucks and sedans from 1970 to 1984. Featuring the aggressive Magnum-series 280S grind with 280° advertised duration, 236° duration at .050 in. lift, and 0.460 inches of valve lift at the factory rocker ratio, this camshaft delivers strong mid-range torque with good top-end power across a broad 2,000-6,000 RPM operating range. It is purpose-built for serious street use and mild road racing applications.

The Magnum series profiles are specifically designed for the street enthusiast looking for more power with that unmistakable performance sound. The 110° lobe separation angle produces responsive throttle behavior and a noticeable performance idle that signals serious intent without being unmanageable for regular street driving. As a solid swinging follower cam, this profile matches the factory overhead cam rocker arm valvetrain configuration of the L-Series engine, requiring periodic valve lash adjustment at 0.012 in. intake and 0.012 in. exhaust. The cast iron construction provides excellent durability and wear resistance that the L-Series valvetrain demands.

Important installation notes: aftermarket valve springs are required to support this cam profile - stock springs are not adequate. For optimal results, COMP Cams recommends complementary modifications including exhaust headers, revised rear end gear ratios, and a torque converter upgrade for automatic transmission applications. Stock components are generally incompatible with the increased duration and overlap of the Magnum cam series, so supporting modifications are essential to realize the full performance potential. Assembly lubricant is included for proper cam break-in protection. This camshaft is sold individually - valve springs, retainers, and other supporting valvetrain components must be purchased separately. COMP Cams offers free expert technical assistance to help match supporting components to your specific L-Series build.
