I got this answer too. I got myself a vacuum gauge and set my timing at my highest vacuum from intake port at 700 r.p.m. runs great.
The 96 Impala LT1 uses an optispark ignition system in which timing is controlled by the PCM (Computer). In order to change the timing you would need to use a computer, cable, and a tuning program such as PCM4Less or Tunercat. The Optispark mounted on the front of the engine is non adjustable for timing controls. The timing is controlled by the PCM sending signals to the ignition control module located adjacent to the coil on the passenger head.

There is no timing screw, simply a key the fits in both the crankshaft and flywheel that provides the proper alignment between the two for ignition at the proper time.
A 2003 Impala does not have a timing belt. It has a chain.
It reads the vibrations that result from the ignition of the air fuel mixture in the engine. The computer uses that information to calculate proper ignition timing.
No. It positions the flywheel in the proper place for the ignition timing.
The 3.5 litre V6 engine in a 2009 Chevrolet Impala has a timing CHAIN

it has a timing chain
On a 2001 Chevrolet Impala : Both the 3.4 and the 3.8 litre V6 engines have a timing CHAIN
( No ) the 3.8 litre V6 engine in a 2004 Chevrolet Impala has a timing CHAIN
In a 2005 Chevrolet Impala : No , both the 3.4 and the 3.8 litre V6 engines have a timing CHAIN
