It really depends on which intake you have...some are set up for either a spread bore or Holley/Edelbrock(square bore).
Chances are, tho, you'll need an adapter. Then, you're gonna have hood clearance issues.
You can use a Holley carb with the original air cleaner base, depending on which carb you get, or want to use. The stock base won't work with a double pumper carb, but...they did use some pretty large Holley carbs on the LT-1 engines, so you may be able to find a base for one of those, and be okay.
