The 2300 was a 2.3 L/140 in³ (2287 cc) straight-4 automobile engine produced by General Motors from 1971 through 1977. The Vega engine, as it became known, was unusual for the time with an aluminum block and cast iron SOHC head. Road & Track reported at the time that this highly-anticipated engine was "a letdown" and "extremely rough and noisy". In addition, an advanced feature of the engine, the fact that it did not have cast iron cylinder liners to stand up under wear but instead used silicon impregnated into the aluminum, did not hold up under use and the engines quickly developed a well deserved reputation for wearing the cylinders into an oval shape and burning oil. ...more on Wikipedia about "GM 2300 engine"
