The L88 427 c.i.d. engine is one of the most powerful Chevrolet big-block engines ever produced, and it was only available for a short time. The engine is most famously tied to the L88 Corvette from 1967 to 1969, and only 216 L88 Corvettes were manufactured during those years. The L88 Corvette was designed to be race-ready right out of the showroom, with over 550 horsepower, and its engine is now highly sought after.
Identify the Corvette as an L88. The L88 is very rare and fetches upward of $100,000, Remember, there were only 216 manufactured and the 427 L88 engine was only used in these Corvettes. Because of their value, many Corvettes from 1967 through 1969 have been falsely labeled as L88s, so comparing different engine codes is the only reliable way to identify the L88 427.
