There is much more to drag racing than just the motor. My best advice would be to purchase and read through a book such as this one to get an idea of the whole picture.....
Drag Racing 101: From Building Your First Race Car to Securing Sponsors: Ike Heckler Jr: 9781450514903: Amazon.com: Books

As far as what BBC to use, Gen VI. One-piece rear seal, 4-bolt mains and factory roller cam.
