This matched valvetrain package combines a hydraulic roller camshaft with compatible roller lifters to deliver a performance-oriented combination for street and performance applications. The camshaft features 0.480-inch lift at both the intake and exhaust valves, with 258 degrees of duration on the intake and 266 degrees on the exhaust, providing a balanced profile for strong engine response across the operating range.\u003cbr\u003eThe 110-degree lobe separation angle supports a responsive powerband and performance-focused engine character. With a recommended operating range of 1,200 to 4,800 RPM, this Xtreme Energy profile is designed for engines that need usable low- and mid-range performance rather than an extreme high-RPM-only setup. The hydraulic roller design helps provide consistent valve action while reducing the maintenance associated with mechanical lash adjustment.\u003cbr\u003eThe COMP Cams CL31-491-9 kit is designed specifically for Small Block Ford applications and provides the convenience of installing the camshaft and lifters as a coordinated package. It is a practical choice for engine builders and enthusiasts completing a street performance, restoration, or mild competition build. Always verify engine compatibility, valve-to-piston clearance, spring specifications, pushrod length, and related valvetrain requirements before installation to ensure proper fitment and reliable operation.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eXtreme Energy hydraulic roller camshaft and lifter kit from COMP Cams\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned for Small Block Ford engines\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e0.480-inch intake lift and 0.480-inch exhaust lift\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e258 degrees of intake duration and 266 degrees of exhaust duration\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e110-degree lobe separation angle\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRecommended operating range of 1,200 to 4,800 RPM\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMatched camshaft and hydraulic roller lifter package for streamlined installation\u003c\/li\u003e\u003c\/ul\u003e","brand":"COMP CAMS","offers":[{"title":"Default Title","offer_id":48724571488478,"sku":"COMCL31-491-9","price":1724.64,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/7690\/8766\/files\/COMCL31-491-9.jpg?v=1787952223","url":"https:\/\/www.racingsupply.ca\/products\/comp-cams-cl31-491-9-comp-cams-cl31-491-9-xtreme-energy-hydraulic-roller-camshaft-and-lifter-kit-for-small-block-ford","provider":"Racing Supply Co.","version":"1.0","type":"link"}
