The 1957 Chevrolet Corvette Big Brake Airbox Convertible represents the zenith of early Corvette performance and rarity. This specific model, identified by VIN E57S104355, stands as one of a mere 43 examples produced with both the factory Big Brake and Airbox options, making it an extraordinarily significant piece of automotive history. Having undergone a comprehensive ground-up restoration and awarded the prestigious NCRS Top Flight recognition, this Corvette is poised to capture the attention of discerning collectors at the Indy 2025 event on Friday, May 16th. Its documented racing history in the Southwest further enhances its allure and provenance.
Engine and Performance: This exceptional Corvette is powered by a potent 283 cubic inch V-8 engine featuring Rochester Ramjet fuel injection, delivering an impressive 283 horsepower. This “one horsepower per cubic inch” marvel is further enhanced by a solid lifter camshaft, contributing to its high-performance capabilities. The power is channeled through a close-ratio 4-speed manual transmission, offering a direct and engaging driving experience. Notably, this Corvette was ordered with the Regular Production Option (RPO) 579E fresh air Airbox intake, a special plenum that fed cool air directly to the fuel injection unit via a duct in the driver’s side fender well, optimizing engine performance. Furthermore, it was equipped with RPO 684 heavy-duty brakes and suspension. This package included specialized front and rear springs and shocks, a heavier front stabilizer bar, a quick steering adapter for enhanced handling, metallic brake linings for superior stopping power, finned brake drums to dissipate heat, fresh air ducting to the rear brakes for improved cooling, and distinctive “elephant ear” front brake scoops to direct airflow to the front brakes. Corvettes ordered with these two performance-oriented options were essentially factory-built race cars, designed for competitive driving. The presence of an 8000 RPM tachometer mounted to the steering column further underscores its performance intent. To minimize weight, the radio and heater were deliberately deleted from the factory.
The exterior of this rare Corvette is finished in the classic Polo White with contrasting Silver coves, a timeless color combination that highlights its iconic 1957 styling. The comprehensive restoration has undoubtedly brought this finish back to its original luster. The inclusion of a hard top adds to its versatility and collectibility. The significance of the Big Brake and Airbox options cannot be overstated, as they were specifically aimed at enthusiasts and racers seeking maximum performance from their Corvettes. The “elephant ear” brake scoops are a visually distinctive feature of this package.
The interior is elegantly appointed in red, creating a striking contrast with the exterior. The focus on performance is evident in the deletion of non-essential items like the radio and heater, emphasizing weight reduction for competitive driving. The presence of the 8000 RPM tachometer mounted on the steering column is a clear indication of this car’s performance-oriented nature. The fact that this vehicle was located in Tennessee by renowned Corvette historian Jim Gessner adds another layer of credibility and provenance to its already impressive history.
This 1957 Chevrolet Corvette Big Brake Airbox Convertible is an exceedingly rare and historically significant automobile. Its status as one of only 43 produced with these specific performance options, coupled with its comprehensive restoration, NCRS Top Flight award, and documented racing history, makes it a truly exceptional find. The combination of its high-performance 283/283 HP fuel-injected V-8 engine, 4-speed manual transmission, and the specialized Big Brake and Airbox packages creates a driving experience unlike any other. Its appearance at the Indy 2025 event presents an unparalleled opportunity to acquire a blue-chip collectible Corvette with a remarkable pedigree.
