What is the timing setting on a 1993 Chevy 1500 pickup with 350 engine?

There isn't a single "timing setting" for a 1993 Chevy 1500 350. The timing is controlled by the computer (ECM) on these vehicles, and it's not adjustable via a distributor. The ECM adjusts the timing dynamically based on engine conditions like engine speed, load, and temperature.

Trying to adjust the timing on this engine using traditional methods (like rotating the distributor) will likely result in damage or a no-start condition. Any timing-related issues should be addressed by a qualified mechanic or using professional diagnostic equipment. They can check for potential issues with the ECM, sensors, or other components affecting the ignition timing.
