Re: 96 blazer timing off
ok so back to the basics:
1. recheck thiming chain marks(make sure that #1 cylinder in on T.D.C. of the compression stroke. 2. Then make sure the distributer is pointing at #1 tower of cap. If u feel that all the above is and has been done,keep posting with more detailed info.

Re: 96 blazer timing off
You do not check it with a timing light,hook up a scan tool and go into the data stream looking for cam sensor retard,the spec is 0 degrees.The distribitor on a vortec 350,305,4.3 and 454 is set with a scan tool.
