“The Chevy II name was dropped in 1969, and the car was now known simply as the Chevrolet Nova. For the next few years, the changes would be primarily limited to engines. The end of the 327 and (brief) availability of the big-block 396 cid (6.5-liter) in 350- and 375-horsepower versions came in 1969. In 1970, Chevrolet added a 300-horsepower 350 for the Nova SS and a 255-horsepower version for lesser Novas. A few SS models were fitted with the new 402 cid (6.6-liter) V-8, though the cars still carried 396 badging and the same 350/375-horsepower ratings as the "real" 396. The 402 and the four-cylinder were gone for '71, as was the smaller six, and the 350 V-8's power output began to drop as new emissions regulations took hold.”
