{"product_id":"81-series-performance-camshafts-v12","title":"81 Series Performance Camshafts V12","description":"The SpeedCams TJP81V12 is a pair of performance camshafts engineered for V12 cylinder engines. These high-performance components are specifically designed and intended for competition use only, offering enhanced engine operation.\n\nThe 81 Series camshafts boast precise specifications: an inlet lift of 0.490 inches and a duration of 279, coupled with an exhaust lift of 0.480 inches and a duration of 269. These figures indicate a significant upgrade in valve timing and lift for increased power output.\n\nInstallation of these competition camshafts requires specific modifications. The tappet guide must be notched to ensure clearance for the cam lobe. Additionally, it is recommended to use Competition Valve Springs JA005 \u0026amp; JA006 to maintain a minimum of .50 inches above coil bind, ensuring proper valve train function under high-stress conditions.","brand":"SpeedCams","offers":[{"title":"Default Title","offer_id":52866368995640,"sku":"TJP81V12","price":1897.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687683377.jpg?v=1787906897","url":"https:\/\/store.motormia.co\/products\/81-series-performance-camshafts-v12","provider":"MOTORMIA","version":"1.0","type":"link"}
