Triple Diamond Award Winning 427/435hp C2 Corvette Muncie 4-Spd Well-Documented

Chevrolet saved its best for last in 1967, and when that meant a Tri-Power 427 rated at 435 horsepower in a lightweight C2 convertible, the result was nothing short of outrageous. This example backs that reputation with serious credentials, documented by its original Protect-O-Plate and a Triple Diamond Award earned in 2019, an honor awarded by the Muscle Car and Corvette Nationals to Corvettes that have achieved both NCRS Top Flight honors and Bloomington Gold Certification. Restored to factory specification in 1992 and refreshed in 2018 prior to judging, the car has since been shown and housed in climate-controlled collections, reflecting the level of care and scrutiny required to achieve and maintain those honors.

Finished in correct Goodwood Green with a white convertible top, the car presents with a high standard of fit and finish consistent with its award history. A painted white stinger hood signals the presence of big block power, while side dual exhaust reinforces its period-correct performance intent. Panel alignment, trim, and brightwork reflect careful restoration and preservation, and 15" Rally wheels wrapped in Toyo Extensa radial whitewall tires provide a traditional look with improved road manners. The overall presentation highlights a well-executed and highly regarded example of a big block C2 convertible.

Power comes from a 427ci L71 V8 featuring Tri-Power induction and a matching partial VIN, factory rated at 435 horsepower. Backed by a matching VIN Muncie 4-speed manual transmission and a 3.70-geared Positraction rear axle, the drivetrain reflects the top-tier performance configuration available in 1967. The car is further equipped with F41 suspension, date-coded shocks, and four-wheel disc brakes, combining period-correct components with the capability expected from Chevrolet's most potent Corvette offering of the era.

The green vinyl interior has been restored to a high standard, featuring a matching green dash and door panels that complement the exterior finish. A chrome shifter, factory-style AM/FM radio, and 3-spoke wood-grain steering wheel complete the cockpit, maintaining an authentic appearance consistent with the car's documented restoration and judging history. The overall presentation reflects careful attention to detail throughout.

Documented with its Protect-O-Plate, NCRS Performance Verification, and Triple Diamond Award recognition, this 1967 Corvette represents a highly scrutinized and carefully maintained example of an L71-powered C2 convertible. Cars restored and evaluated to this level are increasingly difficult to replicate, particularly with the combination of documentation, authenticity, and award history present here.
