It boasts a 227\/239 duration at .050 lift and .678\/.688 lift with a 1.8 rocker and a 114 CL lobe separation angle.\n\nExtensive engine dyno testing conducted at Lingenfelter has resulted in the development of this camshaft profile, positioning it as a top-tier street camshaft for 427 CID LS7 ZO6 Corvette applications paired with a six-speed manual transmission. It is the same camshaft featured in Lingenfelter's renowned LS7 616 HP and 630 HP engine packages, signifying its proven performance capabilities. The GT19 camshaft is optimized for daily driven C6 Corvette ZO6 vehicles and is also compatible with other 427 CID LS7 cylinder head and intake setups, whether they utilize manual transmissions or automatic transmissions with a loose torque converter.\n\nInstallation of this camshaft requires upgrades to the valve springs and retainers. It is designed to be installed in LS7 engines without necessitating modifications to the stock pistons. Each Lingenfelter camshaft is precision ground by Competition Cams to Lingenfelter's exacting specifications, utilizing induction-hardened cores to ensure superior durability and longevity. The firing order for compatible engines is 1-8-7-2-6-5-4-3, following standard GM V8 cylinder numbering.","brand":"Lingenfelter","offers":[{"title":"Default Title","offer_id":52686626390328,"sku":"L210116006","price":417.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/658756047.jpg?v=1784875427","url":"https:\/\/store.motormia.co\/products\/gt19-ls-series-camshaft-227-239-678-688","provider":"MOTORMIA","version":"1.0","type":"link"}
