Timing is handled by the computer, there is no adjustment needed.
8 degrees
The distributor is not timed with a timing light. The distributor rotor is lined up with the mark in the pick up plate when the crank is at tdc#1. The computer then does all timing from there.
timming just needs to be close the computer adjusts it to what it needs and the points are gone since the early 70's it is electronic with moduales, sensors and such
6 BTDC
12 deg btdc with coolant sensor unplugged
2 before tdc at 1600 rpm vacuum advance disconnected
I beleive the factory spec is 4-6 degrees retarded.
as long as the cam timing is set correctly there should be no reason to check ignition timing because there is no way to adjust it anyway. if there is a spec it should be under the hood on a white label.
advance your timing 6 degrees due to this ethanol crap fuel we run now
0 degrees with vac off and electroniv advance disconected according to the sticker on my hood
what is the timing spec for a 94 camaro 3.4l v6i converted it to carb and points on distributor
6 deg +/- 1 with distributer vacum blocked and idle at 750 +/- 50 rpm
