What is the timing set on a 350 vortex engine?

The 350 Vortec engine doesn't have a single "timing set" in the way that might be implied. Instead, the timing is determined by several factors and is not a fixed, pre-set value like you might find on a distributor-equipped engine.

The critical components determining ignition timing on a 350 Vortec (which uses an electronically controlled ignition system) are:

* Crankshaft Position Sensor (CKP): This sensor tells the Engine Control Module (ECM) the exact rotational position of the crankshaft.

* Engine Control Module (ECM): The ECM uses information from the CKP sensor, as well as other sensors (like the Throttle Position Sensor, Manifold Absolute Pressure sensor, etc.), to calculate the optimal ignition timing for each cylinder, on each engine cycle. This timing is constantly adjusted based on engine load and operating conditions.

Therefore, there's no single timing degree value to quote for a Vortec 350. The timing is *dynamic* and controlled by the ECM. You can't adjust it with a distributor like on older engines. Any "timing" adjustments would be done through ECM reprogramming (often requiring specialized tools and software).
