{"product_id":"comp-cams-magnum-roller-rockers-cb-fc-1","title":"COMP Cams Magnum Roller Rockers CB \/ FC","description":"These Magnum Roller Rocker Arms for Big Block Chevy 396-454 applications are the ultimate street rocker. With a 7\/16\" stud diameter and 1.72 ratio, they are designed for serious performance enthusiasts. All Magnum Roller Rocker Arms are constructed from 8620 chromemoly steel, which is a superior material that will not flex and assures maximum lift. Their roller tip reduces friction, while stiff design and superior ratio accuracy yield more effective valve lift. With a 15 to 30 horsepower increase over other rocker arms, Magnum Roller Rockers are perfect for performance applications with less than 350 lbs. open spring pressure. Don't accept inferior products or cheap knock-offs, look for the COMP Cams logo stamped into the underside of every Magnum Rocker.\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/8a0c0c4bac68d143c077f3d274494faf.PDF\"\u003eUser 1\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/c0860feae79372b76767b54c8619b3a8.PDF\"\u003eWarranty\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/d41d8cd98f00b204e9800998ecf8427e.PDF\"\u003eCatalog\u003c\/a\u003e\u003cbr\u003e","brand":"COMP Cams","offers":[{"title":"Default Title","offer_id":44014077116637,"sku":"CCA1411-8","price":116.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/3758\/1491\/products\/05c4ca66e54f485f2dd5c79980f3c7d4.jpg?v=1691964524","url":"https:\/\/hellhoundperformance.store\/products\/comp-cams-magnum-roller-rockers-cb-fc-1","provider":"Hellhound Performance","version":"1.0","type":"link"}
