What determines early and late 1963 for a Tach Buzzer?
The Over Rev Buzzer Warning System came as standard equipment on early 1963 Corvettes with RPO L-76 340 HP and L-84 360 HP hi-performance engines.
To protect the engine from being over rev'd, this system would sound a buzzer when the engine's RPMs exceeded a predetermined factory setting.
The system consisted of a separate wiring harness and a special tachometer that included a buzzer.
This system was soon discontinued by GM when they realized that the buzzer was not audible at high vehicle speeds. However, the visual warning (red zone) on the tachometer would remain.
Generally accepted as a late December or early January running production change, or in the area of VIN # 4982 - 9465.
