    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.

    Rollin' Thunder Camshaft Features
  • Performance: Higher lift velocity and faster valve action increase horsepower and torque
  • Drivability: Great-sounding idle with excellent vacuum at idle to support power accessories
  • Durability: A roller tappet's small surface area + reduced friction + stronger camshaft material (hardend steel or iron) = long camshaft life
  • Environmental: Can use ILSAC GF-4 oil, which lowers engine emissions and does not require zinc or phosphate oil additives
  • Economy: Reduced contact friction between the lifter and camshaft increases fuel economy for better mileage potential

  • ROLLIN' THUNDER CAMSHAFT KITS
    These complete cam kits feature an Edelbrock Rollin' Thunder Hydraulic Roller Camshaft and Edelbrock Hydraulic Roller Lifters and Pushrods that are dyno-matched for a trouble-free installation. Each kit includes: camshaft, hydraulic roller lifters, lifter guides, pushrods, and hold-down spider (1987-Later applications only). Kits offer great performance gains when matched with the rest of the Edelbrock Total Power Package.
  • Complete kit gives you everything you need to upgrade your camshaft
  • Virtually eliminate break-in problems (no special break-in required over flat tappet cams)
  • Higher lift velocity and faster valve action produce superior horsepower and torque
  • Get more horsepower and torque without sacrificing idle quality and manifold vacuum
  • Reduced friction improves fuel economy
