1980 Corvette Specifications and Statistics

By Tony Griffitts

In 1980 the Chevrolet Corvette was produced with three engines. For all states except California, the 350 c.i.d. (5.7 l) was offered in the L48 (190 h.p.) and L82 (230 h.p.) engine. For 1980, California residents were stuck with the LG4 305 c.i.d. (5.0 l) (180 h.p.) engine since GM did not have a 350 c.i.d. yet that met California Air Resources Board (CARB) requirements. In 1981 a new 350 c.i.d. L81 (190 h.p.) engine was installed that met CARB requirements.

The 1980 Corvette can be easily identified by the one year only emblem affixed to the nose and fuel door. The emblem has a chrome outline, while the 1981 is black.
