The COMP Cams Mutha' Thumpr 235/249 cam in FW configuration provides a high-output street/strip profile, improving midrange and top-end performance. A stock converter is usable, but the cam excels with a 2,000+ rpm stall and matching gearing; intake and header work are recommended. Installation produces a rough idle typical of this family.
