The COMP Cams Mutha' Thumpr 235/249 camshaft kit is tuned for high-output street/strip applications, favoring broad midrange power. While a stock converter will work, the cam performs best with a 2,000+ rpm stall and matching gearing; intake and header upgrades are recommended. Installation will produce a rough idle typical of aggressive cam profiles.
