What holley is this

[rommaster2]

Hello,

I am running a holley 2 barrel on my falcon. It runs great but I'm planning on modifying it to accept boost with a solid float so I can run the turbo I got from Xflow_Fairlane. In order to do that though I obviously need to know what type of carb it is.



Oh and it came off of my sisters 67 289 Mustang.

We need the number that's stamped on the choke housing.
Looking at the front of the carb the number is in the upper right corner, it should say 'list_ _ _ _ ' and another number under that one.

Sorry for taking so long to get it, been really busy .

The carb number on it is 6r1919B.

I found this topic on a IMA modified dirt racing forum:

"All 350 carburetors cast by Holley have a raised casting number on top of the body. This casting number is the primary number that makes the carburetor legal. If your carburetor has the stamped numbers, it will also have the casting number. The stamped numbers are Holley’s part numbers for that carburetor. Holley casts many carburetor bodies, some which they sell to other carburetor companies who then assemble and retail to you. These carburetors are legal for use in a Stock Car as long as they conform to all the carburetor tech tools.
Make sure and check your carburetor for the casting number. It cannot be removed or missing. The 350 Holley casting number is 6R1919B."

It sounds like that Holley is a 350 cfm..........
