Description:
Make some noise with Edelbrock Rollin' Thunder hydraulic roller camshafts. Designed to improve horsepower and torque, they feature more aggressive profiles than conventional flat-tappet hydraulic cams without excessive valve overlap. Recommended for high performance street and strip use, Edelbrock Rollin' Thunder hydraulic roller camshafts work best from 1,500 to 6,500 rpm and are performance matched to Edelbrock Total Power Package components for proven performance.

Features Include:

* Performance--roller camshafts generate higher lift velocity and faster valve action for increased horsepower and torque gains
* Drivability--produces great sounding idle with excellent vacuum at idle
* Durability--the smaller surface contact area of roller tappets and their reduced friction, together with stronger camshaft material (hardened steel or iron) ensures longer camshaft life
* Environmental--can use ILSAC GF-4 oil, which lowers emissions and does not require zinc or phosphate oil additives
* Economy--reduced contact friction between the lifter and camshaft can increase fuel economy for better mileage
