Edelbrock cam 35011/7/2022 ![]() To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. ![]() Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. ![]() WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm. ![]() These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. It features smooth idling for daily driven cars and light trucks.WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. The 2102 cam will optimize low to mid-range torque, from off-idle to 5500 rpm. This is one of Edelbrock's milder cams for 1957-1986 small-block Chevys. Through the years, cam manufacturers have found that many engines prefer more duration on the exhaust lobe than on the intake lobe. These are referred to as single-pattern cams. 050" of tappet lift as a common measuring point, allowing cams from different companies could be accurately compared.Ĭamshafts were originally designed with the same duration and lift on both the intake and exhaust lobes. Over-camming is a common mistake when building a motor.īecause different measuring points are used for advertised duration, the industry established. If you can't decide between two cams, choose the milder one.ĭuration is the number of crankshaft degrees of engine rotation during which the valve is off it's seat.Īs you increase the duration of the cam, you increase the peak horsepower, but at the expense of low end torque.ĭo not to overdo the duration when selecting a camshaft. Too high a lift may also cause interference with the valve head and the top of the piston. This happens when valve spring tension is insufficient to keep the valve following the cam at its apex. To a point, the further the valve rises from its seat the more airflow can be released.Īt very high RPM, valve bounce may result. ![]() In proper sequence, these series of events produce an efficient and strong-running engine. The valve springs push them closed on their return. Lobes on the camshaft push against the push rods and rocker arms to open the valves as the camshaft rotates. This, along with the cam profile, determines the flow of the air/fuel mixture ratio. Vehicle weight, engine compression, cylinder heads, valve size, transmission type, and other factors must all be considered.Ĭamshaft basics start with the relationship between the rotation of the camshaft and the rotation of the crankshaft. Camshaft selection dictates which engine components will work well together. ![]()
