440 build, I need some input

Thanks, I guesse I'm a bit hopefull on the ET, as I said most of this stuff has been sitting in my garage and I am doing this on somewhat of a budget, this is just to get the RB set up in the car, and have a little fun with it. Once I get the Willys finished I wont mind dumping money in the Dart but for now its low buck race car, so you guys think I should add a 1/2 to a full second to my expectations? And what do you think of the Edlebrock RPM intake? (I can get one cheap) and, BG or Holley carb? (I can use this later so I dont mind spending for the carb) I thank you all for your input and advice
