Help identifying my carburetor

[Kipprc]

I have been trying to identify my carburetor for an hour or so with no luck. It has w with a line under it cast on the front side with the numbers 1405 and 1725 stamped on there. On the drivers side the numbers 8867 are on there. On the top there is another W with a big bar under it. I am trying to identify the carburetor so I can buy a book on it and possibly buy another one to train on. I am starting to think this is a knock off. I can match it to anything on identification charts and google has got me nowhere..Thanks in advance for any help you can give me.

Edelbrock 1405 Performer 600 CFM 4 Barrel Carburetor, Manual Choke
Maybe an older one of these?

Maybe. I have no idea. I thought the W underlined was an indicator of Weber or Weiand, but the numbers don't add up. Thats why I was thinking knock off. For now it works. Maybe down the line I will switch to something that is more identifiable. I want to be able to study it and learn it. Then I can make a better on decision if I want to move on to EFI or not. I can't do that if I can identify it.

It's a Weber. They made the AFB for awhile until Edelbrock bought them out.

The identification number you want is the stamped number, not cast numbers
Its probably 4 to 6 digits.
There may also be a date code stamped.

Do some searches. I've seen some listings for Carter numnbers but don't recall where. Might be old FABO posts, or in the FABO how to, or could have been somewhere else...

In the picture above, the number might be stamped on the other pad of the mounting plate also. If it's before Weber & Edelbrock, it will be a 4 digit number followed by a letter or two.

1405 is the performance version of the 600 CFM AFB style carburetor. They were made by Weber, sold through Edelbrock. Same carburetors as Edelbrock sells today. It's not a mystery. It's a performance tuned 600. The sister carburetor, the 1406 is tuned for economy. The 1405 has a richer tune for performance.
