The CL5 is designed for unrestricted classes where high-RPM stability and power matter most. Built to take advantage of modern rule packages that allow ported heads and billet rods, it pulls strong through the 7,000-7,200 RPM range. When paired with DynoCams DCS-VS 10.8 lb valve springs, the CL5 maintains stable valve control at elevated RPM, delivering usable power where other cams fall off. Legal in AKRA, NKA, and WKA unrestricted stock classes.
