    The most popular OE camshaft type through the late 1980s, hydraulic lifter profiles can provide a power curve that tops out just over 7000 RPM when used with high-performance hydraulic lifters. Also easy to maintain, hydraulic cams range from aggressive (rough idle) to towing (improved bottom-end torque).
