Xtreme Energy™ 240/246 Hydraulic Flat Tappet Cam for Chevy Small Block. Very strong torque with excellent mileage and a smooth idle. Xtreme Energy Cams™ bridge the gap between Magnum street cams and race only cams. Xtreme Energy Cams™ provide increased torque, vacuum, response, and power while still providing quiet operation of the valve train and the durability required in daily driven vehicles.

Xtreme Energy™

Benefits:

  • Quicker opening lobe profiles deliver increased responsiveness & more area under the lift curve
  • More vacuum allows a step up in duration for greater performance
  • Best seller; excellent all around performance in street carbureted applications

Important Considerations:

  • Work best with COMP Cams® roller rockers and matched valve springs
  • Require other performance parts (intake manifold, headers, etc.) for best performance
