What are timing degrees on 1981 Datsun 280zx?

Timing degrees on a 1981 Datsun 280ZX refer to the alignment of the engine's crankshaft and camshaft in relation to the ignition timing of the engine. The factory specifications typically call for an ignition timing of around 10 degrees BTC (before top dead center) at idle. Proper timing ensures optimal engine performance, fuel efficiency, and reduces emissions. Adjustments can be made using a timing light to align the timing mark on the harmonic balancer with the timing scale on the engine.
