Photo of Fifth-Gen GM Small Block V-8 Shown by Buffalo Business Paper
Photo Shows Similarities, Differences to Current Small Block V-8
General Motor's 2014 fullsize trucks are highly-anticipated by truck fans. One of the reasons is for what will be found under the hood. GM has confirmed that a fifth-generation, direct-injected small block V-8 will be among the offerings, in multiple displacements.
Specific details of the new powerplants have still not been officially revealed, such as output numbers, fuel economy, and even specific displacements. But we do now have what we believe to be a photo of the fifth-generation small block. The photo shows plant manager Steve Finch standing next to the new engine.
A little over a week ago, a local business newspaper in the Buffalo, New York area did a piece on GM's investment in its Tonawanda, NY facility to add a third engine line to make a new V-8 engine. The fact that Tonawanda would be one of the sources for the new engine was announced more than two years ago.
Similarities to the current fourth-generation small block are readily apparent, with oval-shaped valve covers, and valve cover –mounted ignition coils. But one thing that sticks out, no pun intended, on the new engine, are the prominent "lumps" on the valve covers. There's a good chance these may house the new direct injectors. It may seem counter-intuitive to put the injectors underneath the valve covers, but the placement may help quiet the "clickety" noise characteristic of direct injection, and will not require frequent maintenance and access.
Click the link below to see the photo of the new engine. We've included photos of the current fourth-generation small block in the gallery for reference. What other differences between the fourth and fifth-generation engines do you see?
