How are the Crane hydraulic flat tappet camshafts described? Some would use words like "power," "versatility," "dependability," and "revered." All of those are perfectly acceptable ways to characterize the most popular type of OEM camshaft through the late '80s. The reasons for the strong allegiance are simple and true. The Crane hydraulic flat tappet camshafts' lifter profiles can provide a power curve that tops out at just over 7,000 rpm (when used in conjunction with high performance hydraulic lifters), while offering a history of low maintenance requirements. Crane also provides you with a multitude of flat tappet camshaft choices, ranging from grinds designed to improve bottom-end torque for towing to aggressive profiles with rough idle characteristics that will awaken your innermost horsepower demons. 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.
