The COMP Cams 289DHR-12 hydraulic roller cam is a street/strip EFI profile (237/247) targeting 331–363ci engines with 190–215cc heads, offering midrange power gains. It requires an aftermarket intake and tuning to calibrate fueling and ignition. Recommended compression is in the 10:1–11:1 range; pairing with proper induction and calibration yields the intended street/strip drivability and output.
