Somewhere around 15-20 degrees before it snaps a tooth off, but the timing moves both ways: your timing retards on acceleration and advances during deceleration. Bronze distributor gears are only good for 2000 or so street miles- less if you drag race. Bite the bullet and put a new gear on before you break something 'important' in your motor. Also consider where all that bronze slop worn off the old gear has gone....

You can go with a steel gear and never have to change it again...

I dont, i use a torrington bearing on the cam sprocket and set the endplay at .003 to keep the cam from moving.

...cam buttons are Chebby related and even though the needle bearing timing sets are awesome, they're really not necessary either. I've done tons of SBF/BBF/FE Ford stuff with just regular timing sets, cam thrust plates, and roller cams.

I used to run bronze gears, but the steel gears are a whole lot more convenient these days, and not much more expensive at all.
