im running a stock 360 with a mallory unilite upgrade in the distributor, wondering if anybody is running more than 6 degrees of timing advance?

I am running nearly 16. I will be adding a mallory unit next week in my 360. I will keep in touch as to what I come up with. At 6 deg my 360 could'nt cross the street. At 12 to 16 it has power. I just took it out on a hundred mile run today and it ran awesome even in hilly country and almost 100 deg heat. I am going to check my total advance tomorrow.
It confuses me some too but look at this.

Initial timing is a meaningles number, unless you know what your total advance is.

Look here for instructions on finding your total maximum mechanical advance.

Thanks Bear. That is the same link I posted. My thread was on the same subject so I will just follow this one. One question I asked that didn't get answered is you said to "Keep it safe" Keep it safe from what? What kind of damage are we talking about here. I want to understand whats going on in there. None the less I am going to follow your advice.

Formula,
Measured Gross Advance - Initial Advance = Net Measured Advance. (+ or - timing) for Total Desired Advance of 36. (For a street machine that works once in a while.)

I still don't fully understand the concept so I will be "puttin my siferin" cap on until I get it.

To much timing is never good thing and Ford has always recommended no more than 38° maximum mechanical advance in the FE motors.

To tell the truth I have run as much as 44° total advance, BUT this was under a specific set of circumstances in a racing situation and I never did it on a street motor.
