'63 Corvette was fuel injected....
Mechanical fuel injection. A large air-door/flap in front of the throttle body connected to a fuel valve functioned as a mass air flow sensor of sorts and it was a "constant spray" type of injection where the injectors spray fuel on all 4 strokes (360 degrees) regardless of intake valve position.
The Rochester mechanical fuel injection was an option on 283 and 327 small block chevys from 57-65 in more than just the corvette.
Nothing wrong with modern Sequential fuel injection, a big part of what i do for a living is tuning late model cars (mostly GM but some ford and dodge) and with the technology and computing power nowadays you can really squeeze every ounce of power out of an engine on the ragged edge of blowing with the closed loop fueling, twin independent variable cam timing, knock sensors per cylinder making sure that a 2.7 liter turbocharged gas engine in a 6,000 lbs pickup truck lives (looking at you ford ecoboost) while making 400 ft lbs of torque.
But for me I'm just fine with 4 speed overdrive transmissions and port fuel injection with a damn throttle cable connected to the throttle body and not an electric sensor and motor failure waiting to happen. And my daily driver is a 97 K15 chevy with a 383 small block with a double pumper on it and ill take the 15 mpg on the highway for the mechanical simplicity of it all, can't fix a hung injector in the middle of the swamp 2 hours from the nearest closed autoparts store.
