Original Color: black
Tires/Wheels: Firestone 7:00x15 with RPO 276 5.5 wide wheels
Engine: 283/ 283 fuel injection. This car has the rare RPO579D "AIR BOX". The biggest single engine performance improvement came from the cold air airbox. The airbox (and the internal air filter) was mounted to the driver side inner fender panel and drew cold air from the left of the radiator. This cool air was also split in the box, where the balance was sent thu the driver rocker panel duct to the right rear screened backing plate brakes for cooling. In time it was discoved that the left rear brake overheated more than the right side as the engine was sucking most of the cool air. In 1958, this problem was solved with a complete air cleaner cool air system for fuel injection engines, and a complete upgraded RPO684 cool air induction system for the brake system. On the interior, the tach was moved from the standard location in the center of the dash to the steering column driven directly by cable from the distributor instead of the back of the generator. The airbox option, which was clearly intended for racing, included a mandatory heater and radio delete and, with no radio ignition shielding, this also permitted a more favorable routing for spark plug wires. RPO 579D listed at $726.30. It is believed 50 were authorized and only 43 cars were made. In 2007, 30 survivors have been identified, but some are in question as far as history.
Driveline: RPO 685 Borg Warner T10 four speed was also introduced in 1957. Only 664 Corvette received the new transmission. Vin #3545 appears to be the first production car to get one. There is evidence that early special factory Nassau and Sebring race Corvettes also had the new transmission.

Unique Characteristics: Fifty one RPO 684 Heavy duty suspensions and brake option cars were built in 1957. This option featured all the developments from the January Daytona and March Sebring races, including the HD springs and shocks, a fifth extra leaf in the rear spring, finned brake drums with sintered cerametallix linings, vented backing plate and scoops to catch cooling air. Of special note was an air duct system that ran into the fender wells and through the rocker panels to vent cold air on the rear brakes. 1957 vin # 775, believed to be a Nassau Dec 56 race prep car, but used the 581 brake/ suspension package from the 56 Sebring era. Vin 6338, second from last production is the oldest vin 684 car found to date. It had the 270hp engine from the factory. Paperwork and Doug Hooper and Dick Guldstand remember racing against the car in 1957. The earliest St. Louis production "AIR BOX" 579D car to show up is vin 4007. This Bill Howe racer was picked up at the factory and driven to Cumberland, Maryland for the May 19, 1957 Regional SCCA races. Its fully documented history by racer Jack Knab who was with Bill that weekend. Dr. Dick Thompson, Carroll Shelby and Bill Howe drove the first 3 B/P cars that weekend, all Corvettes. As of 5-24-08, we have found 1 car with #581 suspension, 21 cars with #684 suspension and 30 cars with "Air Box 579D". There are other Corvettes with these options, but their histories are unknown.
Modifications: Added equipment included a roll bar, an electric fuel pump, traction bars and competition exhaust that exited in front of the rear wheels. Headers were NOT used until 1964 in SCCA events.
