i herd on a stock 5.0 you can run 18-21 degrees of timing with premium fuel. im at 14 deg. now but 18-21 sounds bad ***. is that true?

 

it might be...mine isn't stock,but it loved the timing i dynoed at 276 with 14 deg. then bumped it to 18,and it chumped out 304hp.so far i had no pinging took it to the track,drove home with not a hick up,back to the question i did bump my fuel pressure a lil bit,stayed about 12.5.

 

would it hurt to try?

 

Yep. One of my Mustang books said they got the most out of a stock motor with 17 deg. My buddy gets 14.60's with a 3.27 rear, automatic, and high miles. He twists' it up to 17.

 

If you're gonna do it do it very carefully. One degree at a time and notice for anything not feeling right. I wouldn't risk it though, not good for your engine.

 

Just try 1 degree at a time and dont drive nuts. Slowly work it up to wear it runs the best for you. I drove my car and it was way way over 20. Was a accident so i wont say how much but the car didnt break.

 

It's not gonna be an immediate thing, just over long term it will put extra stress on the engine with too much advance.

 

i dont have a stang yet so im not sure on something and this is probably a really stupid question but, how do you change the timing, and why does it give you more hp?

 

the car doesnt make any more power past 14 degrees so just leave it at that

 

You turn the distributor and you can get more power since it changes the detonation point.
