COMP Cams CBVI XR276HR-10 Xtreme Energy Camshaft for 1996-1999 Chevrolet 454/502 Big Block Engines

Featuring a quicker valve opening, the Xtreme Energy camshaft profile provides increased responsiveness and more area under the lift curve than older, slower grinds. Designed to increase performance without sacrificing driveability and creature comforts, the Xtreme Energy grind family offers gains in torque and horsepower while still delivering adequate vacuum for power brakes and other vacuum dependent accessories. Xtreme Energy camshafts work great in carbureted applications, but offer the best performance with aftermarket intake manifolds, lower gear ratios, headers and free flowing exhaust. Great for high performance street machines, needs intake, headers, lower gears and 2000+ stall. 1996-1999 Chevrolet 454/502 GEN VI Big Block
