Need more info. Is it a 2bbl or 4bbl?
It is off of a 73 car such as an LTD or something large.
If it is a 2bbl, it should have a 3 number code stamped on it somewhere like .121 or something similiar.

It's a 4 brl off of a 73 429. I'm told it came out of a Lincoln hurse. The previous numbers and letters is just what's left on the data tag.

Are all 4 barrels the same size or are the front small and the rear really large?

They appear to be the same size, may be slightly larger (haven't gotten out the caliper)

I'm pretty sure that it is a 600cfm. Those are pretty good carbs. I used to run one on a 351C when I had my 71 Torino Cobra.

Thanks, I've got a Carter 625 on the 429 now and just wanted to make sure it's enuf carb. I'm having trouble getting the "snap" I thought the engine would make
