The roller cams' ability to quickly open and close the valves allows for more sophisticated camshaft profiles, while the hydraulic lifter body eliminates the need to constantly set valve lash. Crane Cams has the industry's largest database of camshaft profiles. This enables Crane to provide you with the camshaft that's ideally suited for your application. They also have an exceptional \"flat\" power curve and are a popular retrofit into older engines. Crane hydraulic roller camshafts are the starting and ending points for your camshaft needs.\u003c\/p\u003e \u003cbr\u003e\u003cbr\u003e\u003cul\u003e  \u003cli\u003eCam Style:Hydraulic roller tappet\u003c\/li\u003e  \u003cli\u003eBasic Operating RPM Range:3,800-6,600\u003c\/li\u003e  \u003cli\u003eIntake Duration at 050 inch Lift:262\u003c\/li\u003e  \u003cli\u003eExhaust Duration at 050 inch Lift:270\u003c\/li\u003e  \u003cli\u003eDuration at 050 inch Lift:262 int.\/270 exh.\u003c\/li\u003e  \u003cli\u003eAdvertised Intake Duration:332\u003c\/li\u003e  \u003cli\u003eAdvertised Exhaust Duration:340\u003c\/li\u003e  \u003cli\u003eAdvertised Duration:332 int.\/340 exh.\u003c\/li\u003e  \u003cli\u003eIntake Valve Lift with Factory Rocker Arm Ratio:0.680 in.\u003c\/li\u003e  \u003cli\u003eExhaust Valve Lift with Factory Rocker Arm Ratio:0.680 in.\u003c\/li\u003e  \u003cli\u003eValve Lift with Factory Rocker Arm Ratio:0.680 int.\/0.680 exh.\u003c\/li\u003e  \u003cli\u003eLobe Separation (degrees):114\u003c\/li\u003e  \u003cli\u003eCamshaft Gear Attachment:3-bolt\u003c\/li\u003e  \u003cli\u003eComputer-Controlled Compatible:No\u003c\/li\u003e  \u003cli\u003eGrind Number:HR-262\/400-2S1-14 IG\u003c\/li\u003e  \u003cli\u003eValve Springs Required:Yes\u003c\/li\u003e  \u003cli\u003eQuantity:Sold individually.\u003c\/li\u003e \u003c\/ul\u003e","brand":"Crane Cams","offers":[{"title":"Default Title","offer_id":44687231156535,"sku":"CR139711","price":741.15,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/67205.jpg?v=1780422231","url":"https:\/\/enginemaster.com.au\/products\/crane-cams-cr139711-chev-bb-hydraulic-roller-tappet-camshaft-advertised-duration-332-340-lift-680-680","provider":"Engine Master","version":"1.0","type":"link"}
