{"product_id":"stage-2-ls-vortec-truck-camshaft","title":"Stage 2 LS Vortec Truck Camshaft","description":"The Summit Racing SUM-8701 is a Stage 2 LS Vortec truck camshaft engineered to enhance performance in your vehicle.\n\nWith a duration of 218 degrees intake and 227 degrees exhaust at 0.050 inch lift, a 112-degree lobe separation, and 2 degrees of advance, the SUM-8701 offers optimized valve timing. The lift measures .523 inches for the intake and .524 inches for the exhaust using a 1.7:1 rocker arm ratio. Its recommended operating range is from 2,200 to 6,200 rpm. The valve events include an intake valve opening at 1 degree after Top Dead Center (TDC) and closing at 39 degrees after Bottom Dead Center (BDC), with exhaust opening at 46 degrees after TDC and closing at 0 degrees after BDC. This configuration results in -1 degree of overlap at 0.050 inch lift.\n\nThe Summit Stage 2 truck cam is noted as the largest recommended for use with a stock stall converter. While it can function with stock springs, LS6 springs are recommended for optimal performance and durability. This camshaft offers incredible torque right off idle and can be tuned for a smooth idle or a noticeable lope, providing a distinct sound that indicates a cam swap has been performed. It utilizes state-of-the-art cam lobe designs to pull strongly past 6,000 rpm.","brand":"Summit","offers":[{"title":"Default Title","offer_id":52866413363512,"sku":"SUM-8701","price":299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687699401.jpg?v=1787907455","url":"https:\/\/store.motormia.co\/products\/stage-2-ls-vortec-truck-camshaft","provider":"MOTORMIA","version":"1.0","type":"link"}
