The COMP Cams CB XS290S-10 camshaft is a pro street/bracket style grind that requires supporting mods—good intake, headers, gearing and a 3500+ stall converter—to make power. It suits serious street and bracket builds where peak output and strong top-end matter more than a smooth idle. Important: BBC 1965–1966 396 c.i.d. engines with a rear-journal oiling groove will not accept the listed part numbers; contact us for groove-specific options.
