assuming you have a non-electronic timed car, you set the idle speed first, then disconnect and plug the vaccuum line at the distributer (a Golf tee or a pencil works OK), then find the timing mark behind the crank shaft pully and use chalk or white paint to make it visible from above, when above the engine behind the crank shaft pulley there should be a little gauge with numbers use the chalk to mark the correct timing setting. next connect an inductive timing light according to manufacturers instructions (hook it up to the battery and the #1 spark plug wire) then turn on the engine, if the two marks you made line up then your timing is fine, if not loosen the distributer nut and turn the distributer slightly until the marks line up, then retorque the distriburter nut shut off the engine disconnect the timing light and reattach the vaacuum hose. for electronic timing disconnect your negative battery cable, reattach and let it run for 2-5 minutes before driving
how do i set the timing for a chevy 350 small block?

Everything is different in that motor.
The timing chain and gears.

4 degrees advanced, or BTDC.
Need to KNOW the YEAR of the engine. And what it is in.
4, to 6 degrees advanced, or BTDC.
Thay all did in the 80s
in the engine block
That means the timing chain and gears are worn out / to loose.
