Is your mechanical advance working? If so what is the total timing at say, 3000 rpm?

most fords don't like any more total than 32. did you have the vaccum hooked up to the distributor when you checked with the light?

I would absolutely disagree with that statement. Most sbf engines when set up correctly like more ignition timing than sbc's. I'm currently running 38* mechanical timing with an additional 12* of vacuum advance when cruising. Here is a link to a good website of Ford info...

I think its pretty common to run better with more advance than the factory specs. You run into a ping problem if you get too far advanced.

if it's a 289 or 302

The factory setting, "6" on a points car is a compromise choice so the original, stock motor can run "decent" at any altitude/climate/gas/etc.
For tune ups, it says use 8 (a little perkier so the guy knows you did a tune up?)
It further says: "you can increase the base by up to 5 deg from the 6 for maximum performance if the alt/etc allows".
To check your base timing be sure to disconnect and plug the vacuum advance first.
Rev the motor to 3,000 and confirm the total is less than 32-34 with the base at 6 BEFORE you start increasing the base.
Depends on your motor, stock with 87 octane, 10/32-34 is pretty safe.

Need more info on your motor!

dmorris,

???
The article used a Pertronix in place of points for fixed dwell at high RPM, yeah I agree you can run more timing with solid state, I do for mpg on my car.

I myself have ran more without terribly ill results but find that around the 32 mark is where most fords are happiest. Even the newer computer controlled mustangs seem like they like more timing, but the computer actually retards them, so as where some people thought they were running 40-42* total, were actually getting 32-34. Individual cars vary, granted, but the average sbf likes around 32 degrees.
