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. Performance application, great mid-range torque, likes headers. Chevrolet GEN IV 396-454 Big Block Engines Originally Equipped with Flat Tappet Camshafts
