The COMP Cams XE284H cam is a street/strip-oriented profile that needs about 9.5:1+ compression and a 2800+ rpm stall converter, and will produce a rough idle. It favors supporting components such as headers and gearing to reach its powerband. As with other COMP Cams big-block offerings, confirm fitment for 1965–1966 BBC 396 c.i.d. engines with a rear-journal oiling groove.
