The most popular OEM camshaft type through the late '80s, hydraulic lifter profiles can provide a power curve that tops out just over 7000 RPM (when used in conjunction with high performance hydraulic lifters) while offering ease of maintenance. Choices range from grinds developed to improve bottom-end torque for towing to aggressive profiles with rough idle characteristics that many enthusiasts prefer.
