A new build......

I'm starting a new build for drag racing, going bigger, and would like some insight/opinions on a combination that's been around a while. A 572. I've got an aluminum KB block on order. It should be here shortly. I have a set of original B1's with T&D rockers. They've had minor port work done. Mainly to get the same CFM out of each port. I will be running carburated alcohol. Hopefully before too long ill have the info on what the heads flow so I can get a new Bullet cam ordered. Any info or insight would be greatly appreciated.
Oops I almost forgot. It will be going in my 68 Dart(drag race only). It has an ATI powerglide and Dana 60 with Moser internals. It has 4.56's in it now but will be changed over to 4.30's.
Thank you for your time!
