In the ignition system, CCC was fully responsible for the timing curve; mechanical and vacuum advances were eliminated from the distributor.

In an external combustion engine, such as a steam engine, the control of the valve timing is by the valve gear.

The system adjusts both intake and exhaust timing between two settings. This engine produces 403 hp (301 kW) and 417 lb⋅ft (565 N⋅m) in the GMC Yukon Denali/XL Denali, GMC Sierra Denali, Hummer H2, and briefly in the Chevrolet Tahoe LTZ (MY 2008.5 – MY 2009) and rated at 403 hp (301 kW) and 415 lb⋅ft (563 N⋅m).
