Timing on my 76 Blazer
Can someone help me out with the timing and dwell for my 1976 Chevy Blazer 350 automatic 4x4? The underhood diagram is no longer legible due to a small engine fire?

I think you scared everybody off with the word DWELL.... Basically that is the time that the points are closed...
I don't know when GM moved to an electronic ignition but save yourself some time and headache and get rid of points if you have them either with a module to replace them inside your distributor or with a new HEI ignition.
Set base timing between 4* and 12*. All-in timing should be somewhere in the 34* range.
