Chevrolet added a 305-cu-in V8 between the six-cylinder and 350 choices. Z28 is still absent from the factory model/option material.
Type LT and appearance packages carried the showroom story while Chevrolet offered no Z28; any performance narrative should describe the actual engine and chassis equipment rather than retroactively applying the later Z28 comeback.
The powertrain and identification notes below preserve configuration and model-year boundaries rather than treating every 1976 Camaro alike. Ratings use the measurement convention of their period, and visual cues are only a starting point: the VIN, factory labels, drivetrain identifiers, and surviving documentation should agree.
