Is a 570cfm carburetor too small? Also an intake question

I'm in the process of pulling off an old EFI system and going back to a carburetor. From my many years in the classic Ford hobby, I just happen to have a Holley Street Avenger carburetor sitting in my garage. For some reason I was thinking it was a 600 or 650, but decoding the numbers tells me it's actually a 570cfm. I'm thinking it would be a bad choice for the 351 in a Pantera. Any thoughts here?

Also, the car came with an aluminum carburetor manifold, but I have no clue what brand or model it is. The only numbers on it are the firing order on top and the cylinder number on each intake runner.

Without knowing the brand or model, am I really costing myself performance? Everyone likes to save money, but I'd rather use the right combination of parts for the car, even if that means buying something else.

Thanks
