The Leading Edge of Valve Train Technology Comp Cams Xtreme Energy series camshafts can be used in any street or street/strip application where both throttle response and top-end horsepower is desired. These cams are designed to take advantage of the latest improvements in valve train components and the newest developments in camshaft design. Their aggressive lobe design produces better throttle response and top end horsepower than other cams with the same duration @ .050'' lift, while delivering increased engine vacuum. We do not recommend the use of stock valve train components with these camshafts due to the aggressive lobe designs..
