? about timing & timing tab
Does anybody have a picture of the timing tab that shows the #'s? The #'s on my dads 86 Iroc cant be read. Also on the underhood sticker it says the timing should be 6 degrees DR. What does the "DR" stand for?

It should read 6 degrees BTDC or "Before Top Dead Center".("advanced")
And the "0" on the tab is the largest valley notch, and each point going counterclockwise is in 4 degree increments. 0, 4, 8, 12 "advanced"...the valleys between the peaks are, 2, 6, 10.
On the other side (clockwise from "0") is 4, 8 degrees "retarded"
And you must disconnect the single tan wire with black stripe timing connector on the main harness above the heater-blower, when setting timing.
