You don't need dual carbs on a Cobra to get looks or to impress. If you're not used to messing with carbs, I'd stay with a single carb setup.

I`ve got dual quads on my 427 S/O in my other car and have very little problems with them . Having said that , it took almost a summer to dial them in correctly . If you aren`t used to working on multiple carb setups , stay with a single carb .... you`ll be a lot happier . Spend your time driving and not working on the carbs  |

Turkey Pan
You should go with a Turkey Pan -- the car show folks love it and you almost never see it on anything other than a Cobra.

I like my turkey pan, but dual quads and the Dynatek would also open some eyes at the car show.

I've owned my car for 14 years. I started out with the single 4 bbl., Sidewinder intake and turkey pan. It was a great looking combination. However, after several years of looking at other folks 2x4 set ups, I changed over.
I have a pair of Holleys on a Tunnel Wedge intake. It took some fiddling to get them dialed in, but that was part of my learning curve and I enjoyed seeing the little gains and improvements that came with the tweaking. Once the dial-in was done (about 8 years ago) all was good. 
Build what you really want. If you don't, it's probably gonna cost you some more money later on when you look at your creation and think "I wish I had done it differently".  I know what that's all about because I'm still making some changes to the car!

Dual quads are great once they are calibrated correctly, and never fail to impress when you pop the hood. The only problems I have had with mine were caused by me when I tried to tweak them even further for more performance. Get them dialed in by a pro, and leave them alone, they will be fine.

No problems
I have a BT intake and a new set of BJ-BK's from Carls and have had no problems whatsoever. Installed it all, fired it up, adjusted the idles and havent touched them in 2 years. I drive it alot also.

I went through a few carburetors and finally settled on the dual 450 mechanical secondaries, control everything with your foot. I only have 7 inches of vacuum.

Dual fours have a big "wow" factor and are painless once they're dialed in (and dialing them in is pretty painless too). To maintain them requires learning a little bit more about how carbs work, but not much. I, too went with a single four and changed to dual fours...in my opinion, I lost nothing in the performance category and gained a lot in the bling category. I like the 390 cfm carbs for throttle response, but the 600's work well too.
You should put them on to start with if you like them.

Dual Quads
The first 427 in 63 used 2 600 cfm Holleys. I am running the same on mine. When I switched from the single, I ordered brand new issue (by Holley) date code correct and correct part number stamping Holleys that were guaranteed to be wet flow tested and adjusted, ready to run. That is exactly what I found...they fired right up after bolting on. I had the timing reset and adjusted the idle speed a little. I purchased the carbs from Carl's Ford Parts. Check out his website, he may still have some available.
They are very easy to setup. Pretty maintenace free if they are done right and if you purchase good products. Stay away from some rebuilt junk. They do get lots of attention
