The KA24E had a single overhead cam and KA24DE had dual overhead cams. Rubber plug where cam angle sensor would mount. The camshaft was the HO cam with 288/301 duration. There is much in favor of the roller cam brake design. No cam angle sensor on exhaust cam, now located in distributor. The top engine option was a 455 V8, with a hotter cam and W30-style heads. This was the first Falcon engine that came standard with DOHC and Variable Cam Timing. It is an overhead cam, twelve-valve engine. It features VVT for both intake and exhaust cam. Other Cosworth engines based on the Lotus-Ford Twin Cam include the Mk. The impulse coupling uses a spring, a hub cam with flyweights, and a shell. This attribute is beneficial for Phillips screws which are prone to cam out. The second variable moved the follower along the axis of the cam. The output is parallel to the axis of the cam. Lower powered versions only have variable cam phasing on the inlet cam (LE0).
