I'm missing the emission sticker off my car, can anyone tell me what the default timing setting is for a 1985 305 TPI (LB9) Trans Am?

 

I believe its 8*, yet 10* worked better in my car, flew through emissions too. Don't forget to unplug the distributor wire before setting your timing.

the 10 degrees initial would be great.

 

Stock timing is 6*BTDC on an 85 TPI, but I have mine at 10* and it works great.
