The Corvette team decided to one-up the Viper with four extra cylinders, they decided on one of Ryan Falconer’s stunning, all aluminum, 600-cubic-inch, 683hp, 680 lb-ft V-12 racing engines. The biggest challenge was the fact that the all-aluminum V-12 engine was 8.8-inches longer than the production Corvette engine. So the front end of the ZR-1 would have to be stretched 8 inches. This test car was named Conan, after his raw, beastlike charisma.

Despite its popularity, the second-gen Corvette holds the record for the fewest number of production years of any generation Corvette. The most valuable examples of the C2 Corvette live sort of like "bookends" at the start and finish of second-gen production.
In 1969, Chevrolet changed the perception of Corvette forever by introducing the ultra-powerful ZL-1 Corvette with a 427 CI engine producing 585 horsepower! The 1969 ZL-1 Corvette came equipped with an entirely new big-block engine option that produced more horsepower than any Corvette that had come before it. Any Corvette, when ordered with RPO ZL1, came fitted with an all-aluminum 427 C.I. engine that featured a dry-sump oil system and which weight approximately 100 pounds less.
While it was not the rarest Corvette Pace Car Replica ever manufactured by GM, the 1998 Chevrolet Corvette Pace Car Replica was – and remains – one of the most desirable pace car replicas ever made. This is primarily due to the fact that this replica is nearly identical to the actual pace cars that were used during the 1998 Indianapolis 500. It was fitting given that 1998 also marked the brand's 20th anniversary as "Official Pace Car" of this momentous race.
1978 was significant because it marked the cars 25th anniversary of production. Recognizing the achievement of manufacturing a car for a quarter-century, Chevrolet commemorated this accomplishment by introducing two special-edition Corvette that year.  The first of these was known as the "Silver Anniversary" edition Corvette.  It featured a two-tone silver over gray exterior with special pin-striping and special "25th Anniversary" badging.
