what holley carb would this be

I was walking through the brush at this old homestead and found a mid 70s Ford Thunderbird sitting in the weeds. It has a Holley four barrel and was wondering what CFM this would be and if it would be worth getting. I'm guessing the motor is a 429 or 460.

Hmmm, rockauto only shows an Eddy replacement carb or the Motorcraft 4350 spreadbore.
