On "My Car Story" we're at Collectors’ Car Garage in Chicago IL at The Rise & Drive Event on 10-2-16.

We're looking at a 1957 Chevrolet Chevy Corvette Fuel Injection Convertible in Red Paint.

Ramjet Fuel Injection was the big news for 1957. In the continuous spray system eventually produced by Rochester, the nozzle is located directly outside each cylinder, spraying into the intake port. There are essentially only three components to the final system that was installed on 1957s Corvettes: An air meter, fuel meter, and intake manifold. The air meter signals the fuel meter based on engine load fluctuations; subsequently, the fuel meter uses that vacuum control signal to regulate the fuel flow to the injection nozzles, while the intake manifold distributes the rammed airflow.

The final product was a Ramjet fuel injection system that was reasonably affordable to manufacture; increased top-end output; and spread power over a wider RPM band. In practice, the results were staggering: a car that could rev cleanly to 7,000 RPM, yet idle at 900 RPM, enabling a 283hp version to do 0-60 MPH in just 5.7 seconds in a period Road & Track test. Many later had their troublesome fuel-injection setups removed and replaced with carbureted systems, and as a result, the pricey $500 option wasn’t often chosen.

Of the 6,339 1957 Corvettes produced, only 1,040 were fuel-injected. A small, tasteful checkered flag emblem on the fender was the only hint at what lay under the hood to differentiate this potent offering from less rarefied Corvettes leaving unmolested Ramjet Corvettes among the most advanced and desirable sports cars of the era.
