In 1970, GM pushed the performance bar higher with the introduction of the Chevy 454 V8. Unlike the popular Chevy 427 that was used in a wide variety of automobiles, the 454 was used only in high performance cars like the Chevy Camaro, Corvette and Chevelle. There were 3 different variations of the 454 that came onto the drawing board at GM during the 70s; the LS5, the LS6, and the LS7 which was designed but not produced for the general public most likely due to the massive smog restrictions that started lurking about in the early 70s. . Although the LS7 454 never made its way into any cars sold to the public, it was sold as a crate engine available through Chevrolet and claimed to produce around 500 horsepower.
