The Edelbrock Rollin' Thunder RPM hydraulic roller camshaft #2201 targets Chevy small-block engines from 1957–1986 to boost low- and mid-range torque while preserving a smooth idle. It is intended to be matched with Performer manifolds for operation to about 5500 rpm and includes or is supplied with recommended lifter options and installation guidance. Use requires a thrust button, a high-stall converter and stock-ratio rocker arms.
