Does the carb have a choke horn on it? If it does then #'s should be on the front of that, but if not, and the carb is an HP style body (fully radius'd body) then #'s will be on the side of the body (stamped on flat boss areas).
If the carb was built from bare castings by any number of builders out there, then there may be no choke horn and no factory numbers on it, and in that case, those numbers you are seeing are merely that carb builder's serial numbers for that particular carb.
The "4306" doesn't sound like any Holley list number, and the "452" means nothing either, in terms of the standard Holley numbering or date codes.
If you can describe the carb in more detail, I can help with what or who's carb it is.

Is it a 4bbl? 2bbl? does it have center hung bowls, or side hung? What numbers are stamped on the butterflies underneath? Any numbers on the baseplate out near the bolt holes? Do the boosters angle downward or are they straight leg ones with center/cross bars across their middle? Is it a vacuum secondary carb or mechanical w/ 2 accelerator pumps?


Need more info and we can help ya out.

Thanks for the compliment on our work, too. :-)

Ahhh....ok. I didn't realize from the PM that this what the same conversation/question. Sorry, ignore my reply in PM then. :-)
That's an OEM Holley 2bbl carb. It is not meant for racing, but can surely be made functional for your application that you described. I don't have my "big carb book" in front of me, but I can look up the # tonite and let you know specifics if you like.

If that is the rpm limit you're setting, then that carb you have will feed the motor just fine. You probably will want to go up in jet size one step or so and possibly alter the fuel restriction sizes, but really, with what you're running, the carb will function just fine to that rpm range.
