Is there a web site to search for specs on holley carbs? I had one given to me and need to find out what it is. The only numbers I can find on it are 12R 10552B. It has vacuum secondarys and no metering blocks or removable float housings. The top comes off such as a stock Motorcraft carb does. I've never seen one of these before.

Holley numbers are usually right outside the opening on the top of the carb where the air filter sets down on. Inside your round circle. Hope that helps.

Their PDF file of carb listings won't have that number. That looks like an actual baseplate casting number and not a list number on the carb. If it's not on the choke horn, or on a tin tag attached to it, it's best to take a picture maybe.
Holley tech might be of assistance, but just from what you've described it almost sounds like the old "Economizer" 4010/4011 series carb. They discontinued them years ago.

Not a race carb, by any means....
