Edelbrock LD4B intake manifold

Can anyone tell me if the Edelbrock LD4B intake manifold will fit on the early 273. I have a 1965 Barracuda with a 273 and want to change the 2 brl. manifold for a 4 brl. Will the LD4B work without modifications or do I need the D4B?

Thanks, any help would be much appreciated.
