Re: 96 vortec 5.7 timing questions
Hey, figured I'd answer your question! The timing for your year and model of engine state "Cannot be adjusted; Electronically controlled" So the best thing I believe you can do is to find TDC the old fashoned way, set your first spark on that and let the cpu do the rest.
An earlier year for that same engine states TDC as the first spark point so you can't go too wrong.
Good luck and let us know how it goes!
