Xtreme Energy camshafts are a best seller due to their excellent all-around performance in street applications. Increased responsiveness and more area under the curve are delivered due to quicker opening lobe profiles. More vacuum is created which allows a step up in duration for greater performance. COMP Cams roller rockers and matched valve springs work best with this camshaft. Other performance parts are recommended (intake manifold, headers, etc.) for best performance.
The Xtreme Energy XE256H camshaft provides strong torque throughout the low-end and mid RPM range with a good idle.
