1965 Corvette Performance & Specifications

Powertrain, Steering, Brakes, Dimensions, & Suspension

While this small-block engine was an impressive powerhouse in its own right, Chevrolet had definitely recognized that the direction of the powerplant for the Corvettes would center around engine displacement, and so it was decided that all other, smaller engines would ultimately be abandoned in the Corvette line at the end of the 1965 model year. Interestingly, the retirement of the 327ci engine also brought with it the end of the use of fuel injection in Corvettes for the next twenty years.
