Important Application Information:
Rollin Thunder Hydraulic Roller cams are for street high-performance and racing applications only - not for heavy vehicles. Use with Edelbrock Performer RPM heads (or other aftermarket heads), adjustable valvetrain components, screw-in studs, high performance adjustable rocker arms and at least 9.5:1 compression ratio. Headers, high-energy ignitions, lower-than-stock rear gearing and a high-performance torque converter (in auto. transmission equipped vehicles) are necessary.
|ROLLIN' THUNDER CAMSHAFTS|
Edelbrock Rollin' Thunder Camshafts are designed to improve horsepower and torque, produce a great sounding performance idle and provide sufficient vacuum at idle to support power accessories. Compared to conventional flat tappet hydraulic cams, Rollin' Thunder Camshafts have more aggressive lift profiles without excessive valve overlap that can compromise low-RPM drivability (reduced friction provided by roller tappets makes this combination of accelerated valve lift and reduced duration possible). Edelbrock Rollin' Thunder Camshafts are performance matched to Edelbrock Total Power Package components for proven performance.

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. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. 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.
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. 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. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. 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.
