Xtreme Energy 224/230 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.
