This is the factory camshaft for the 5.7L HEMI with variable valve timing. On these engines a cam is usually replaced because of lobe wear that has already taken out a lifter, so the two go together as a job. The grind is specific to the VVT calibration, which is why the part number matters more than the displacement.
