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.
with the terminal unpluged for the electronic advance 0 degrees.
Need to replace the electronic timing controll module. It is mounted over by the left valve cover, But bolted on the intake.
Whenever someone has trouble timing a Chevrolet V8 engine, the cause for the problem generally points to a stretched or worn out timing chain & gears. Make sure that all timing advance mechanisms are disabled. Depending on the age of the vehicle in question it may be as simple as plugging the vacuum line to the distributor, or as difficult as disabling the advance circuit of the engine control unit. If all advance systems have been disabled and you find it difficult to set the timing accurately, inspect the timing chain for stretch.
The timing should be set to Top Dead Center (TDC), but you must disconnect the electronic spark advance feature. Unfortunately, I don't know how to disconnect the spark advance. The timing chain is all that can be set. There is no way to set the timing as the distributor is not adjustable.
the timing shoujld be 8 degrees BTDC. If your engine has a vacume advance hose running to the distributor than you will have to remove it from the distributor and seal it off before setting the timing.
There were not any timing belts in 1966. The timing should be set at 4 degrees before top dead center. With the base timing, the centrifical and vacuum advance all together should be 35 degrees.
