DP carbs with automatics

holley mech double pumper carbs aren't really that hard to deal with. I wouldn't use one without a 3500 rpm and up convertor, though. I have one on my 383 (72 duster) and it works pretty good. You just have to play with accelerator shooters until you can floor it without a bog. A vacuum carb will sometimes never get the secondaries fully open due to the spring, air cleaner design, air filter volume, etc. So I personally think that a mech carb is the way to go if you really want to wring every hp out of your combo. But that's my opinion.
