How do I tell what type of Holley I have? The previous owner couldn't remember if it was a 600 or 650 cfm Holley. Is their something that would give it away? Like a serial number.

 

The model # is etched on the side of the choke horn, between the primary and secondary barrel.

 

I couldn't find a number other than 11076.

 

That Holley has been modded since it's missing the choke butterly. The model # should be etched on the secondary side of the plate that divides the primary and secondary venturi. It should be a 4 digit #, some models have a dash and a 5th digit.

If this is an RB modded carb, they most likely removed the model #. From what I can see in the pics, it appears to be a manual choke dual feed carb. If the carb has replaceable metering jets in the secondary block, it's a 4150 model. If the jets aren't replaceable in the secondary metering block, it a 4160.

The metering block is the thin piece between the main carb body and the float bowls.

 

It has replaceable jets. Right now it has .66 But once its fully broken in I was told to take it to .64.

 

Do you see any numbers on the front of the choke housing?

 

^ Sorry I'm carburetor illiterate. Which is the choke housing?

 

Looks like a 650 double pumper.

 

Also will the racing beat intake fit on this holley?

 

yea! isnt that what its sitting on?

 

^not the manifold. I'm talking about the intake filter assembly.

 

RB makes 2 filter assemblys. One for the Nikki and one for the Holley.

 

oh! my bad!

 

here are a few pics to help you out.....

 

Thanks RXnos1200. I found the part number

80670-1
1542

But its definitely been modified.

 

Looks like you have a Holley Street Avengers series carb; 670 CFM with vaccum secondaries.

 

Based on the linkage it looks like a double pumper not a vac sec. But hey I have an Edelbrock......what do I know!

 

The black square with the Holley sticker is where the housing for the secondary diaphram is. I see the screw they inserted to help open up the secondaires with. That vaccum housing would be gone if the accelerator pump and pump cam rod is there to make it a Double pumper. It can be converted to a double pumper easily though.

Hey Latin. I would love to try an Edelbrock carb one of these days.
