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.
what is recomended when replacing timing chain in 99 blazer with a 4.3 v6
It has a timing chain.
That requires the use of an OBDII engine scanner. The timing is electronic controlled and the OLD timing light will not work.
It does not have one. You can not use a timing light on that year engine. The timing is computer controled. You MUST have an engine scanner to set the timing.
A broken timing chain is a possibility.

It should be 6 degrees before tdc, just make sure you disconnect the distributor's computer control wiring harness before you adjust, and check the timing with a timing gun.
