Re: carb help

Yeah, thats a Holley. I'm not sure what its off, That big part hanging off the side looks like a governer. It might be off a big truck like a C-60 . I remember seeing a carb that looked like that on a 69 C-60 dump truck equipped with a tall deck 427.

I would guess its rated around 700 cfm.

Re: carb help

We had a real hard time figuring out what mine was, so I went to holley.com and sent them an email asking what I had. Gave em the numbers and all, and they sent me good info about it.

Re: carb help

no idea what carb it is, but if it won't fit your intake, several companies make an adapter to go from the spread bore pattern to the square bore holley pattern.

Re: carb help

Look for a small stamped number on the choke plate. Most Holleys stamp the model number there.

Re: carb help

Look at the horn surrounding the choke. Look at it from the front, on the right side of the horn. List the numbers here and that will make it easy.
