My dad was under the impression it was a 750 or 780 Holley Spread boar (Holley with Q-jet bolt pattern, small primaries, and large secondary). It is a vacuum advance Holley, but I am not sure what size. In an old holly number list I have I found a 0-7005-2 that says it is a 650 CFM, is this correct?

does anyone else have a source to look this up?

BTW on the choke it reads:
LIST-7005-2
2699

Thanks,

To my knowledge, Holley doesn't make a 750 spreadbore, just a squarebore.

650 sounds about right.

 

My guess is that if the Holley listing matches it with a 650 cfm, then that is probably what it is. If I remember correctly, Holley did make a spreadbore carb in an 800 or 850 cfm, but I'd still say that this one is likely a 650. You might try and search the web for their website and see if they have any more info.

Hope that helps!
