I have used Summit Racing cam SUM-6401...224/234@.050 w/.465/.488 lift but it has very little low end torque but pulls great on the topend. I used and old 383 Torker with it on a stock low compression 400 from a Cordoba. I even used the stock valve springs. No coil bind. You will need low rear gears and a high stall converter 
I used this cam in a tired 400 in my '66 Charger. Best run was 8.85 in the 1/8th mile. Nice little cam

Comp 268 single pattern will go right in the 14s with ease. just get the right curve on the dist and that baby will haul
My 7.5 comp 360 73 Sat just ran a string of mid 14s Saturday with a 4,350 racing weight and 3.91s

14's in a 4000 lb car can be done with a rerung 360, 4bbl, headers, comp XE262 and 3.55's. BTDT
if you're not planning on swapping pistons out of the 400, I'd probably look at a voodoo 60302 or a comp XE262.

I have a good running 360 thats been rebuilt recently with flat top cast pistons and the heads have been milled...I didnt do it myself it came in a truck i bought but we had the engine apart and regasketed it and it looked like new inside...I was thinking maybe the 400 would get me farther ahead then the 360 but maybe not?? The car its going in is a pretty much stock J body and i plan to switch out to a 8 3/4 with etheir 3:55s or 3:91s....

mine was a rerung dished piston '79 with a little home porting by me on the heads, RPM air gap, eddie 1406, comp XE262, comp 901 springs, cheapie headers, low gear 904 (later A500) MP 166K lockup converter, 3.55's in a B body 8.75, 27" tires in my 5th ave, that is 3950 without me. it was conservatively a low-mid 14 second ride. would keep up with a bone stock 5.7L 300C.
I sold the motor and replaced it with a roller cammed, mag headed 318, lost a little low end, but no top end. the lost low end could be switching back to the stock 1200 stall converter after finding a crack in the hub of my 166K (which stalled ~2300-2400 behind the 360)
I'd use the small block, it'll be much easier, don't have to mess with the radiator or tranny.

With the 3.55's I would run the XE 262 or similar.You need torque to move the barge.You could step up to the 268 with 3.91's and be ok also.
I would swap the DP for a 750 vacuum secondary with a quick change secondary kit to tune the secodaries by stiffer/lighter spring.
The 400 will outperform the 360 but you will swap a lot of stuff to get it there.
Consider a spreadbore carb if mileage is a concern.
The snappiest combo would be with the 262 cam and 3.91 gears.Would'nt need a stall and would pull to 5200(ish)rpm with ease.
I run the XE262H Comp Cam in my 383, 727,, 2200 stall, 3.73 gears. Pulls good thru 5600 RPM's. I shift at 5700. For me it's a little on the small side. With a 400 I'd go with the Comp Cam or Voodoo 268. That would make a fun street cruiser.
