Holley Street Avenger 670cfm to big for 318cui?

Hi,

i have bought some new parts for my stock 1969 Plymouth Barracuda, 318 small block with 4 speed manual.

I read the following article:
https://www.streetmusclemag.com/news/common-upgrades-for-an-la318-in-a-1971-dodge-dart-swinger/

Therefore, I decided to also buy the 670cfm Holley Street Avenger.

After searching some more information I am now unsure about the decision.

Is this carburetor too big for my 318?

I have bought the carburetor at Summit. Should I send it back and get a smaller one?
Which one would you recommend for my setup?
