These cars are unique in many ways, convertible frames, L37 396-375hp,
HD 1.06" front stabilizer. 160 mph speedometer, 11 inch HD brakes.
Although it was the ultimate performance 65 Chevelle, the package was not just performance oriented with luxury, items such as: tachometer, four-speaker AM-FM Multiplex stereo, dash-mounted clock, rear seat belts, instrument panel pad, and remote control outside mirror.
One item that seems odd is positraction was not included and the pedestrian 331 axle ratio.
Perhaps our resident expert Jeff Helms could chime in, since he is a walking, talking encyclopedia on Z16 and other chevelle models. Infact he owns a car, I always loved his red survivor Z16. He has a few other Z16's as well.
