{"product_id":"chopacabra-camshaft-for-gen-3-4-ls-4-8l-6-0l","title":"CHOPacabra Camshaft for Gen 3\/4 LS 4.8L-6.0L","description":"The Texas Speed CHOPacabra is a performance camshaft designed to provide significant power gains and an aggressive, snarling idle for 1999–2013 GM Gen 3 and 4 LS-based truck engines. With a 214\/222 duration at .050\" and .550\"\/.550\" lift, it uses proprietary lobe profiles that allow it to run with factory GM LS6 beehive valve springs, offering a cost-effective path to improved engine performance.\n\nThis camshaft features a 3-bolt timing gear pattern and is optimized for use with factory torque converters, making it a drop-in friendly performance upgrade. It is intended for engines with a compression ratio of 9.5:1 or higher and operates within an RPM range of 1200-6500. For 6.2L engines and 2007-later rectangle port 6.0L engines, a dual valve spring kit or PAC 1218 springs (or similar) is recommended due to heavier valve weights.\n\nInstallation notes are critical: DOD\/AFM-equipped engines require a DOD\/AFM delete kit, and VVT-equipped engines require a VVT delete kit. Furthermore, engines originally equipped with a 1-bolt camshaft will require a 3-bolt conversion kit for proper fitment. Professional tuning is required to achieve the expected performance results.","brand":"Texas Speed","offers":[{"title":"Default Title","offer_id":52663972725048,"sku":"TSPCHOPacabra","price":377.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687141372.jpg?v=1784331385","url":"https:\/\/store.motormia.co\/products\/chopacabra-camshaft-for-gen-3-4-ls-4-8l-6-0l","provider":"MOTORMIA","version":"1.0","type":"link"}
