Pontiac Cam 280H (Hyd)

The Pontiac Cam 280H (Hyd) from COMP CAMS is a purpose-built hydraulic flat-tappet camshaft engineered for Pontiac V8 engines seeking reliable mid-range performance and street-duty reliability. This cam is designed for enthusiasts and mechanics restoring or upgrading classic Pontiac powerplants who demand proven durability without sacrificing drivability. Whether you're rebuilding a stock 400 or 455 or tuning a modified street engine, the 280H delivers consistent valve lift and duration that balances throttle response with everyday usability.

The 280H designation indicates a moderate lift profile and duration curve optimized for hydraulic lifter systems, eliminating the need for manual adjustment or preload tuning common to solid-lifter designs. COMP CAMS manufactures this camshaft with precision-ground lobes and hardened steel construction to withstand repeated cycling and high-rpm stress, while the hydraulic design automatically compensates for thermal expansion and valve train wear. The flat-tappet profile ensures compatibility with stock or mildly modified valve train components, making installation straightforward for most Pontiac engine configurations without requiring extensive machine work or exotic valvetrain upgrades.

Mechanics and restorers working on second-generation or third-generation Pontiac engines will appreciate the 280H's plug-and-play reliability and documented track record in street applications. Installation requires standard camshaft replacement procedures: timing chain removal, careful lobe inspection during break-in, and verification of valve clearances. This cam pairs effectively with stock or aftermarket intake manifolds, standard carburetion, and factory exhaust systems, making it an ideal choice for drivers prioritizing dependability and rideability over peak horsepower. For any Pontiac V8 restoration or mild performance build, the Pontiac Cam 280H (Hyd) delivers the predictable, proven performance that serious enthusiasts and professional mechanics rely on.
