{"product_id":"ls7-stage-3-v2-hydraulic-roller-camshaft-1","title":"LS7 Stage 3 v2 Hydraulic Roller Camshaft","description":"The BTR LS7 Stage 3 v2 Camshaft is a high-performance upgrade for naturally aspirated LS7 engines, designed to unlock significant power gains. Developed in-house by Brian Tooley Racing, this camshaft utilizes new BTR lobe designs that have undergone rigorous Spintron and engine dyno testing to achieve optimal power delivery and maintain valvetrain stability and durability.\n\nKey specifications include a 237\/25X duration, 0.662\"\/.662\" valve lift with a factory rocker arm ratio, and a 114-degree lobe separation angle. This camshaft is intended for street\/strip applications and is known for delivering substantial top-end power. However, users should expect a rougher idle and a potential reduction in low-end torque compared to stock or milder camshafts.\n\nInstallation of this camshaft requires specific supporting modifications and considerations. It necessitates the use of an aftermarket torque converter and is recommended to be used with BTR's .660\" Lift Platinum dual spring kit, which includes steel retainers, and hardened pushrods. For maximum performance and longevity, using titanium intake valves is also strongly recommended to prevent excessive wear on the OE titanium intake valve tips, a potential issue with aggressive camshaft profiles and stock rocker arms. Lash caps or valve tip savers are also advised.\n\nCrucially, custom tuning is mandatory after installation to optimize performance and ensure proper engine operation. Remote tuning options are available through BTR, or users can opt for custom tuning at a local dyno shop. The expected performance gains from this camshaft are significant, with an advertised increase of 96+ horsepower and 20+ lb\/ft of torque.\n\nThis camshaft is specifically designed for LS7 7.0L engines, including the 2006-2013 Z06 Corvette and the 2014-2015 Camaro Z\/28.","brand":"BTR","offers":[{"title":"Default Title","offer_id":52687277556024,"sku":"BTR-LS7STAGE3","price":409.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660190055.png?v=1784882141","url":"https:\/\/store.motormia.co\/products\/ls7-stage-3-v2-hydraulic-roller-camshaft-1","provider":"MOTORMIA","version":"1.0","type":"link"}
