Make some noise with one of these Edelbrock Rollin' Thunder hydraulic roller cam, lifter, and pushrod kits. They feature a hydraulic roller camshaft and improved hydraulic roller lifters that have more aggressive profiles than conventional cams without excessive valve overlap. They do this by testing and tuning them together on engine dynamometers for maximum performance. There's no guesswork about part compatibility with the Edelbrock Rollin' Thunder hydraulic roller cam and lifter kits, and you can be sure that all of the combinations will perform. Recommended for high performance street and strip use, the Edelbrock Rollin' Thunder hydraulic roller cam and lifter kits work best from 1,500 to 6,500 rpm and they maintain good vacuum at idle.
