I'm not %100 sure, but with a stock 400 in a heavy 73 Charger with 3.91's, maybe 5.5 or 6 seconds? You'd need decent traction, and probably a higher stall torque converter to get there.
Your goal is doable though I think. Especially if you go the 470 or even a 505 route since it really doesn't cost much more.
Speed cost money, how fast you wanna go?
I'm talking warmed up to about 400 hp.
400HP from a 73 400 is more than warmed up. Warmed up is a header, intake, carb, small hyd cam (less than 230*@.050). 350Hp is more realistic.
The 2.76 gear is fine, IF you have enough motor.

Was going to add aluminum heads to the combo you mentioned maybe that's not considered warmed up, but would the combo you mentioned plus aluminum heads get me closer to 400 hp?
1973 Dodge Charger SE 400 automatic transmission. Curb weight: 3800 lbs. All stock so far.
Goal: Reliable everday driveable warmed up 400 as close to 400hp as possible, then a 470 stroker if need be.

Seriously? Drove From Memphis to San Diego with 4.10 gears and no overdrive.
NO PROBLEMS.
But it wasn't my momma's car I was driving either.
I'm not saying you can't, and I guess it doesn't bother some people. I have a '80 Mirada with 3.91's and long trips at 3500+ rpm and the loud exhaust get on my nerves after a while. I never had a problem but I guess I worry too much with the engine buzzing for hours like that. 
I had 3.55's in my 5th ave and hated it....cruise at 75mph (5 over on the freeway here in MI) was ~3200 RPM with 27" tires and lockup tranny. my exhaust wasn't too loud, but my ears were ringing after 1/2 hour....adding an OD helped a lot (A500)
FWIW, a stock brand new charger R/T 5.7 will pull ~5.4-5.6 0-60 and 13.5-14.0 1/4 mile time...a brand new SRT8 charger will be about a second faster in each....
it would take a very pretty warmed up 400 with some deep (3.91-4.10) gears to match a stock brand new R/T...
if you still want it drivable on the highway, I'd look at adapting an A518 (46RH) tranny--the .69 OD would make 3.91's feel a lot like your 2.76's on the highway, while increasing your first gear torque multiplication by 42%

Sixty foot time is the number most associated with chassis efficiency...aka hook. It's the quarter mile elapsed time (ET) that matters. A 12 second car will generally have a sixty foot in the 1.6-1.8 range.
Bragging...I have been .910 to the sixty foot timer many times.
and to 100 mph in 1.1 seconds, not 1.2 but 1.1 seconds.
So I guess that's about .6 tenths of a second to 60 mph.
Can you imagine getting on the freeway with that much speed? 
0-265 mph in 5.49 seconds for me personally. 
Oh yea the hemi is 12" behind my head, it's kind of loud.

Ok so more like 6 seconds with aluminum heads, cam, intake, headers, exhaust?
