I got a holley 4bbl out of some guys garage for free, and im thinking about rebuilding it and replacing my Qjet with it. Only problem is i have no idea what CFM the thing is. There is a part number 4585 stamped into the top of it, and it has an electric choke on it. can anyone id this thing?

I already checked that list and the number wasn't listed. Thanks anyway though. Anyone know someplace else i can check?

Well if it's a Holley carb, and it's not on Holley's web site, then either you've got the wrong number, or something.

The number you want will be on the front of the choke stack on the air horn, driver's side, it will say "LIST XXXX" the Xs are the number you want.
