{"product_id":"5-7l-hemi-vvt-performance-camshaft-1","title":"5.7L HEMI VVT Performance Camshaft","description":"The Modern Muscle Xtreme 5.7L HEMI VVT Performance Camshaft is a performance-oriented upgrade engineered specifically for naturally aspirated 5.7L VVT HEMI engines. By optimizing the engine's breathing, this camshaft produces a more aggressive exhaust lope and substantial power gains compared to factory profiles. It is specifically optimized to perform across a wide 1800-6400 RPM range, making it a reliable choice for street-driven performance builds.\n\nTechnically, the camshaft features a lift profile of .591-inch for the intake and .581-inch for the exhaust (using 1.65 ratio rockers) with a duration of 214\/224 @.050. To achieve these performance targets, this camshaft requires specific supporting modifications, including an upgraded valve spring kit and an MMX 8-degree limiter to ensure proper operation within the VVT system. Custom tuning is required to calibrate the engine management system for these new operating parameters.\n\nFor optimal results, high-flow exhaust modifications such as long-tube headers are highly recommended. Installation is a technical process that requires careful attention to valve train compatibility and timing verification; professional installation is suggested for those without experience in overhead valve engine timing. Please verify all local and state emissions compliance requirements in your area prior to installation.","brand":"Modern Muscle Xtreme (MMX)","offers":[{"title":"Default Title","offer_id":52689275879736,"sku":"MMP-214-224HPT+","price":549.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687391383.jpg?v=1784904472","url":"https:\/\/store.motormia.co\/products\/5-7l-hemi-vvt-performance-camshaft-1","provider":"MOTORMIA","version":"1.0","type":"link"}
