Xtreme Energy™ 200/206 Hydraulic Roller 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
