A fixture assembly includes a primary gage member, camshaft gages, a crankshaft gage and an engine gage, all of which have planar datum surfaces that are each dimensionally located relative to the primary gage member planar datum surface. The engine gage includes an engine datum surface, and is sized and shaped to receive, support and dimensionally locate the engine. An engine block datum surface is configured to be positioned on the engine datum surface thereby locating the engine relative to the primary gage member datum surface. The primary, first, second and engine datum surfaces are fixed in a parallel relationship to each other so as to form a parallel alignment system such that when the fixture assembly datum surfaces engage and form parallel alignment with the corresponding engine datum surfaces, the camshafts and crankshaft are angularly located in a predetermined angular orientation for proper timing of the engine assembly.

An intake control system for a multi-cylinder combustion engine with control valves positioned within intake passageways that can vary the cross-sectional area of the intake runners to increase air intake velocity at low engine speeds. The control system includes an inner frame that can be inserted into a lower manifold after manufacture. The inner frame includes a plurality of flapper valves that are actuated by a four-bar link design, which is driven by a hypoid gear-set. The control system controls an internal DC electric motor that actuates a worm-drive gear-set, which in turn drives the hypoid gear-set to either engage or retract the flapper valves within the intake passageways.
