Gev V Engine

 When we last reported on the upcoming Gen V engine, about the most we knew for sure was that it would be direct injection. Most speculation pointed towards smaller displacement as well that would help cut down on fuel consumption, and better comply with CAFE standards. From the exterior the Gen V bares striking resemblance to the Gen III/IV with a few exceptions: the intake manifold, valve covers, exhaust manifolds, and lower pulley. This lower pulley is most likely an external oil pump, for a dry sump system or just relocated to make room for other equipment. The exhaust manifolds have large holes in each primary, which most likely are used for O2 sensors for precise, individual cylinder control over fueling. The valve covers we can only speculate might be part of the next generation Displacement On Demand aka Active Fuel Management (to deactivate cylinders for better gas mileage). Since the intake manifold no longer holds injectors this was the perfect time to make some revisions to it, and hopefully improve the looks on the truck version. Stay tuned for more news as it becomes available.
