What is the timing setting for 2000 chevrolet pick up 5.7 L

You cannot adjust ignition timing on the 5.7 liter V8 vortec engine. This system uses the distributor as a camshaft position sensor. You can loosen the distributor and rotate it, but it adjusts something called Camshaft Retard Offset. This can only be checked and adjusted using a scan tool that can read the cam retard offset parameter. Otherwise, you\'re flying blind. If you have a scan tool that can read it, the retard offset should be set to 0 degrees with the engine fully warmed up and running at 1000 rpm. If you cannot adjust it to 0 degrees, the distributor may be off a tooth or two, and will need to be correctly re-timed to the engine.
