315 crank with CAI and Ford crappy tuning for the Bullitt package.
I can easily see +25 HP gain on a stock 4.6 3v with only a cai + LT's + good custom tuning
with a good cam + LT's + CAI + tuning you should see +30-40 HP gain.
edit: whoops, forgot this was in reference to a blower + LT's. add about +10-20 HP gains when joined with a blower.

I think you're taking it the comments too literally...
The underlying assumption here is that with any LT combo you're going to need a tune, which will in turn, maximize the HP gains. Simply bolting on new headers will not maximize your results.
I've seen a few (maybe 3 or 4) dyno graphs on various Mustang forums that support numbers that Stkjock and others have indicated.

If you take an already tuned car and slap a set of long tube on it, you're NOT gonna see a ridiculously high gain as other are claiming. That is the ONLY true test of a performance product. PERIOD!
Like I said, I don't BS customers or friends. I shoot straight as possible. I let the results speak for themselves.
This is a marketing ploy that has become all too damn common in my opinion. The same goes for using CRANK HP figures. Who in the hell cares how much HP a mod makes at the crank. What makes it to the ground is the ONLY thing that counts.

There is absolutely NO WAY LT header will gain 40 RWHP!

I seem to remember one of the major mustang mags doing a LT header comparison tets on a newer supercharged Mustang last year. It may have been a gt500, but I do remember the best performing headers were the Kooks and ARH's, both with right around 40hp peak gains.

If headers alone would net 40 RWHP ALONE, I'd sell 20 sets daily!
