Abstract: A valvetrain assembly for an internal combustion engine includes a first camshaft, a first intake cam, a second intake cam, a first cam slide member, and a first actuator. The first camshaft rotatably is supported by a cylinder head. The first intake cam and a second intake cam are disposed on and engaged with the first camshaft for common rotation. The first cam slide member is fixed for common rotation with the first and second intake cams. The first cam slide member has a pin groove disposed on the outer periphery of the first cam slide member. The pin groove includes a first side wall and a second side wall opposite the first side wall. The first actuator has a first and a second pins. The first and second pins are individually extendable into the pin groove of the first cam slide member.
