Featuring Rochester mechanical fuel injection, the 283ci V8 was rated by Chevrolet at 283 horsepower when new. The fuel-injection plenum has been replaced with a later-style unit, and results from a June 2019 inspection conducted by Rowley Corvette Supply. Shifting is performed by a replacement four-speed Muncie manual transmission sourced from a 1963 Corvette, which routes power to a 3.70:1 differential. The five-digit odometer currently shows 57k miles, with total mileage unknown.
