1958 Corvette Specs
PErformance is a sports car’S pedigree
A true sports car must handle with precision and corner with positive control. It must withstand long periods at high rpm without a wimper. It calls for a superior suspension and an enviable ratio of power to weight. Corvette is all these things and more, a comfortable tourer, rally car, and trial car. Only when you lay your hand to its helm and toe to its throttle will you fully learn its prowess!
The Heart of the 1958 Corvette
Designed by engineers who built the industry’s first high-compression V8-s the 283-cubic inch (4.6 litre) Corvette V8 is the very heart of its sports car performance. This is the world’s first mass-built engine to develop so much power for its size- up to more than one horsepower for each cubic inch of piston displacement, a hitherto unachieved goal. Its admirable power and torque characteristics center on a rigid, extremely compact block, an ultra-short piston stroke, and advanced overhead valve layout. And for ’58, buyers could command its scintillating response in any of four great versions- ranging up to 290 horsepower.
Ramjet Fuel Injection- Unsurpassed Performance This motoring first gives you instantaneous throttle response, greater power, faster warm-ups and greater overall fuel savings. Fuel is pressure-injected directly at each cylinder intake port, eliminating the carburetor entirely! Optional at extra cost with Powerglide, or 3-speed or 4-speed Synchro-Mesh transmission.
