Buick 350 Hyd. Cam 268H

The COMP Cams Buick 350 Hydraulic Cam 268H (MPN 92-203-4) is a high-energy hydraulic flat-tappet camshaft engineered for small-block Buick and Rover V8 engines seeking reliable mid-range performance and drivability. This camshaft delivers 0.469 inches of lift on both intake and exhaust, with a 268-degree duration profile and 110-degree lobe separation angle, optimizing power delivery between 1,500 and 5,500 RPM for street and light performance applications.

The symmetrical valve lift and duration specifications create a balanced powerband ideal for vehicles prioritizing streetable characteristics over peak horsepower. Hydraulic roller technology in this profile ensures consistent valve actuation across varying engine speeds and loads, reducing maintenance concerns associated with older mechanical designs. The 110 LSA provides adequate overlap for efficient scavenging while maintaining low-speed torque and throttle response. This camshaft is compatible with factory or aftermarket hydraulic roller lifter systems and works within standard small-block Buick induction and exhaust configurations.

Built for Buick 350 engine builders, restorators, and V8 enthusiasts upgrading from factory camshafts, the 268H provides noticeable performance gains while preserving reliable idle quality and part-throttle drivability. This profile is popular in mild to moderate street builds where balanced power delivery and engine longevity take priority. Each camshaft is manufactured to COMP Cams' specifications and is sold individually.

Small-block Buick camshaft selection depends on engine displacement, induction type, compression ratio, and intended use. The 268H sits in the conservative-to-moderate performance range, making it suitable for engines running 8.5:1 to 9.5:1 compression and standard or mildly modified fuel-delivery systems. Proper installation requires accurate timing set to OEM specifications and verification of valve clearance at operating temperature.
