A lot of people go to 14*, but I'm pretty sure you need to use 92-93 octane gas...

Yeah, I run 92 about once every 3 tanks, and then 89 or 87 normally. No "need" for high octane on a low compression v-8 like a stock stang's.

Yeah 14* seems to be optimal for most people(including me) i use 91 octane all the time its the highest where i live but i also have other reasons besides timing to use higher octane.

i agree, i run mine at 14 but if you dont run high oc. it might ping some. just valve chatter. i suggest advancing just a degree or 2 over the stock 10 degees. start at 13 and goup a degree or 2 at a time and ride it down the road and check for pings. soon as you get just a little pinging or chattering it should be just right when you throw the high octane to her. when you do if it still has a little chaatter yoou can barely retard it till it quits. youll probably be about 13 to 15 degres. good luck

yea...duh, use a timing light and unplug the spout connector before you start it. im just saying, keep advancing it till it pings then put 93 in it and it should be aight.
