Quick question guys!

What is the correct dwell and timing for a 1969 Camaro Z28?

Thanks much!

28-32 Dwell angle..4 degrees BTDC.
Hey set your hot idle at 900RPM.

And be sure and set your dwell first.

"Dwell effects timing, but timing does NOT effect dwell."

Why thank you gentlemen!
Now if I could only get the car to idle right...

You will probably want to have the advance curve set up for best performance. The factory curve, timing, and jetting had emissions in mind for sure. Our 427 had #68 jets in the primaries and had a lean surge at 60 mph. A good tuneup on a dyno is money well spent.
