The factory setting is still a good place to start, although you can increase the timing 2 degrees at a time until peak performance is achieved, or until the engine starts pinging.
10 degrees
Your engine has distributor-less ignition. The spark timing is controlled by the ECM, there is no provision for adjustment.
The total timing advance on a 1995 Chevrolet 350 engine should be around 35 degrees. This takes into account the advance provided by the ignition system.
The base ignition timing for a 1974 Chevy 454 engine is between 8 and 12 degrees below top dead center. A timing light is needed to accurate set ignition timing.

The Chevrolet 4.3 liter V6 engine has a timing CHAIN
18436572 same as all Chevy v-8s that is the firing order, not the ignition timing. timing varies between vehicles. a sticker under hood will give timing info, or a Haynes or Chilton service manual
There is no provision for setting the ignition timing. The timing is set by the computer by way of engine sensors sending signals to it by such things as temperature, load, speed, and intake air.
You don't set timing on a carburator or are you asking the timing on the motor
