Xtreme Energy 224/230 Hydraulic Roller Cam

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.

• Excellent performance in street carbureted applications.
• Best performance with aftermarket intake manifolds, headers, lower gear ratios etc.
• Quicker opening lobe profiles deliver increased responsiveness and more area under the lift curve.
• More vacuum allows an increase in duration for improved performance and assists power brakes.
