{"product_id":"brian-tooley-racing-camshaft","title":"Brian Tooley Racing Camshaft","description":"The Brian Tooley Racing BTR-64HEMIVVT-STG2 camshaft is engineered for Gen III 2009+ Hemi applications, offering a significant performance upgrade. This camshaft features a 228-degree intake duration at .050 lift and a 24X-degree exhaust duration at .050 lift, with a .611-inch intake lift and .609-inch exhaust lift. Its 111 LSA (Lobe Separation Angle) contributes to an aggressive idle quality and a broad operating range of 2000-7000 RPM.\n\nThis camshaft is designed to delete MDS (Multi-Displacement System) or enhance the performance of 6.4L HEMI engines. It is compatible with stock torque converters and aims to provide noticeable power gains while maintaining drivability. Rigorous spintron and dyno testing have validated its performance and durability. Brian Tooley Racing specifies that OEM valve springs cannot be used with any BTR Camshaft, and a BTR aftermarket spring kit is highly recommended due to the high valve lift and increased RPM potential. Additionally, all 6.4L vehicles with automatic transmissions require Non-MDS lifters, with the exception of the Challenger 6.4L 392 with a manual transmission.\n\nThe installation of this camshaft requires a VVT Limiter (BTR-VVT-HEMI-4CAM), which is included with the camshaft. However, a separate VVT Limiter Installation Tool may be needed if not already possessed. Proper calibration with attention to detail is crucial for this camshaft to perform optimally. The expected gains from this cam swap are over 50 horsepower and 46 ft-lbs of torque, along with an additional 500 RPM of operating range. This camshaft is suitable for Naturally Aspirated applications and is made in the USA.","brand":"BrianTooleyRacing(BTR)","offers":[{"title":"Default Title","offer_id":52687296627000,"sku":"BTR-64HEMIVVT-STG2","price":449.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662156902.webp?v=1784882322","url":"https:\/\/store.motormia.co\/products\/brian-tooley-racing-camshaft","provider":"MOTORMIA","version":"1.0","type":"link"}
