Comp Cams' New 4-Pattern Cam Boasts Advanced NASCAR Technology

A new series of hydraulic roller camshafts from Comp Cams delivers four different grinds on the same stick to equalize airflow on 4-barrel manifolds. Called the 4-Pattern, the new cams draw heavily from Comp’s experience with NASCAR teams. They’re available for small- and big-block Chevys and small-block Fords.
