Olds V8 Cam 260H (Hyd) 260-455

The Olds V8 Cam 260H (Hyd) 260-455 from COMP CAMS is a high-energy hydraulic flat tappet camshaft engineered for Oldsmobile V8 engines seeking reliable mid-range performance and efficiency. Built for enthusiasts and engine builders who demand dependable valve actuation without the complexity of solid lifter systems, this camshaft delivers consistent lift and duration across both intake and exhaust strokes. The hydraulic design eliminates valve train noise while maintaining precise control over fuel mixture and ignition timing windows critical to street performance.

This camshaft features 0.447-inch lift on both intake and exhaust sides with a 260-degree duration specification and 110-degree lobe separation angle, optimizing power delivery from 1200 to 5200 RPM. The hydraulic flat tappet design uses passive lash adjustment through hydraulic lifters, reducing the need for frequent valve clearance checks and simplifying installation. COMP CAMS' high-energy profile maximizes combustion efficiency and scavenging without requiring extensive porting or head modifications, making it an ideal upgrade for stock and mildly modified Oldsmobile V8 platforms.

Engine builders and street performance enthusiasts working on 260–455 Oldsmobile V8 blocks benefit most from this proven cam profile, particularly those prioritizing drivability and reliability over extreme RPM capability. Installation requires removal of the timing cover and existing camshaft; direct bolt-in compatibility with OEM hydraulic lifters and standard Olds timing chains ensures straightforward retrofit. Pair this camshaft with quality valve covers, gaskets, and a fresh oil change for optimal long-term performance and valve train longevity.
