COMP Cams XE250H-10 Xtreme Energy Camshaft for Chevrolet 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. Very strong torque, excellent mileage, smooth idle. Chevrolet GEN IV 396-454 Big Block Engines Originally Equipped with Flat Tappet Camshafts
