{"product_id":"comp-cams-ford-small-block-camshaft-complete-kit-fs-xe276-hr10","title":"COMP Cams Ford Small Block Camshaft Complete Kit FS XE276 HR10","description":"The COMP Cams Xtreme Energy camshaft delivers enhanced street performance for Ford Small Block engines, offering strong midrange torque and horsepower gains with a smooth yet noticeable idle and responsive throttle—ideal for mild performance upgrades. Designed for street machines, it performs best with proven combinations including the Edelbrock RPM Air-Gap intake manifold, headers, and a TCI Breakaway torque converter (2200–2400 stall) paired with a 3.73 gear ratio, producing a slightly rough idle and improved overall drivability. Featuring full-size base circles, this camshaft works seamlessly with COMP Cams Evolution hydraulic roller tappets and eliminates the need for dog bones and lifter retainers—components never intended for pre-1985 applications. This camshaft supersedes part number K31-442-8, delivering a dependable upgrade with balanced street and performance capability.","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":50943028166713,"sku":"CCAK31-494-9","price":1523.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/4220\/0889\/files\/4f78b83512464a02ea003acacdd601b3L_f6915a61-cc57-4309-a76d-876beef8bb1e.jpg?v=1792887697","url":"https:\/\/chesapeaketrucks.com\/products\/comp-cams-ford-small-block-camshaft-complete-kit-fs-xe276-hr10","provider":"Chesapeake Trucks","version":"1.0","type":"link"}
