Replacement Carb for a 70 340

Hi everyone!
Current I have a Carter AVS Carbon my 70 Duster 340. I’m looking to replace it. It seems that the Edelbrock AVS2 Street Series (1905) is a strong possibility. Also I have seen the Edelbrock Performer series (1405) as a possibility. I know this has been beaten to death but I would appreciate your comments. If I go with Edelbrock is there any other accessories that I will require?

I‘m leaning towards the Street Series.

Thanks
Stu.
