ya i was just wondering, on my stock engine if i were to advance my timing how much of a difference does it make. Will i be able to feel the difference. Also how much hp would i gain??? Thanks:) 
This isn’t the best info here
Mods: cherry bomb, removed bottom half of intake box(pretty much stock)
i went to the track for the first time and just before i left, i advanced my timing by hand(no timing light). I was havin’ trouble with my timing ever since i put my new distributer in, so i didn’t really care too much. Well, i got to the track, and for my first 6 runs, i couldn’t get below a 16.7(91 octane). then, i decided to adjust my timing a little more, and for my next 5 runs, i was consistently .4 seconds below my average.
So…, i don’t know exactly how close my timing was to 18 degrees BTC, but i set it with a timing light before i adjusted it by hand and my car was running like poo. This just makes the point clear that timing definitely makes a difference. I suggest you just try it, and take er’ to the track or dyno. I was definitely surprised at the difference in times by adjusting it a little by hand.(I don’t suggest adjusting it by hand though- i’m an idiot and i just wanted good times while goin’ to the track for the first time with some people in the club around here).
Good luck to ya.
I saw some dyno pulls somewhere a while back. It was something like 1-3 hp on a stock engine.
