I just came by a two barrel intake and carb from a civvy 230. I've heard that one of these setups can greatly improve performance, mileage, etc.

The carb that came with the intake is the proper Holley 2bbl model 2415 but it's kinda beat up looking.

Question is, will this manifold accommodate any 2 bbl carb or is is just for that model? Is there a newer/better carb to use?

I know, dumb question but, you never know till you ask.
