Amc Cam A-280h-10 (Hyd)

The Comp Cams AMC Cam A-280H-10 (Hyd) is a hydraulic flat tappet camshaft engineered specifically for AMC V8 engines seeking reliable mid-range performance and smooth operation. This camshaft is ideal for enthusiasts and builders who prioritize dependable power delivery over extreme RPM capabilities, making it a natural choice for street-driven vehicles, truck restorations, and classic muscle car builds that demand consistent, manageable cam profiles without the complexity of solid lifter designs.

Built by COMP Cams—an industry leader in valve train technology—this hydraulic camshaft features symmetric 280-degree duration on both intake and exhaust with 0.490-inch lift per cylinder, creating predictable, repeatable power across a 2000–6000 RPM operating band. The 110-degree lobe separation angle (LSA) provides excellent overlap characteristics and drivability while the hydraulic design automatically adjusts for wear and temperature variations, eliminating the need for frequent valve clearance adjustments. Flat tappet design ensures proven durability and straightforward installation on stock or mildly modified AMC engine blocks without requiring upgraded lifter hardware.

This camshaft performs best in street and light-duty performance applications where versatility and ease of maintenance outweigh maximum displacement or boost potential. Installation requires standard timing chain and gear sets compatible with AMC V8 engines; buyers should verify block and head configurations before ordering to ensure proper fit. The 10.62-pound unit integrates seamlessly with factory-style valve covers and intake manifolds, making it an excellent upgrade path for those modernizing older AMC powerplants while preserving original engine architecture and reliability characteristics.
