23 degrees, depending how much boost your running
I have searched numerous threads on this topic and it appears 23* in the upper RPM range is the best combination for an eaton pulley'd cobra running 93 octane. Some run more and some run less but it appears that is probably your best number for power/reliability/safety.
I am sure some of the tuners will chime in.

I run 18 and you can see my numbers in my sig.
advance it till it pings then back off 2 degrees.
Each car is going to be a bit different depending on your cooling syste, power level and what heads you have will have an impact. Often times I have seen people report little to no gains from 20 to 23 deg timing. if your getting virtually no gains, why run the extra timing?
Its has stegs newest port, 2.76+2lb, lfp he, 60lb injectors, bap, sct 2400, mid pipe, c/b, cai. My local tuner pulled the previous tune(mail order) and said it was running 23 degrees. This was with the 2.76 only, no port, inj, bap, lower, or sct2400.I'm just wondering if 23 degrees is safe for a dd.
Yep, 23 degrees is just fine. Like others have said though, sometimes 23 dosen't necessarily make that much more power than 20-21, so it's not always needed. It is safe for 93 octane though...
23 Deg timming here tuned by Rick @ Amazon.
He told me as long as I use fresh 93oct. then 23 is very safe for DD.

Same here. Rick is the man!

23* in upper rpms with 16 lbs boost.
Upper only 23* timing is great!
how much power is to be had from advancing timing from 18* to 23* then with a 2.76 upper only, current 456/470?
If those are you numbers at 18* I'm sure you can net an extra 15-20+ rwhp for sure at 23*.redfire03 svt said:
Yes those are my numbers with 18* of timing, interesting.
Yeah, I'd say you'll net atleast a solid 15rwhp by bumping the timing up. Don't take my word for it though... I'm no tuner!redfire03 svt said:

Max timing depends on a whole bunch of things that there's no point in going into. But one thing I thought worth bringing up has to do with maximum-brake torque timing. Once you go past it, power starts to drop so it certainly doesn't make sense to run more than that from the performance point of view as other have noted. But it's worth pointing out that running more than MBT timing is also very bad on the engine whether you've reached the knock limit or not. Just something to keep in mind.
