Description:
Why are Performer RPM cam and lifter kits the heart of the Total Power Package? Because Edelbrock designs them to perfectly match the powerband of their Performer RPM series of intake manifolds. They do this by testing and tuning them together on engine dynamometers for maximum performance. There's no guesswork about parts compatibility, and you can be sure that all of the combinations will perform. The kits are recommended for high-performance street and strip use. Their powerband is from 1,500 to 6,500 rpm, and they maintain 10 to 12 in. of vacuum at idle.
