I am gathering pieces together for a big block and I came across a carb.

Someone has milled the airhorn off, so there are no numbers.

It is a mechanical secondary, double pumper, dual feed, with the numbers 11170 on the primary metering block.

I think the only item of real value is the throttle bores are 1.625 in ID for all four.

Any guesses as to the CFM? It is a fairly simple carb and looks pretty clean.

Thank you for any help.

Sounds like a 750 to me. Holley is big on fractions, not decimals. 1 11/16ths" bore should be a 750, although .625 = 5/8ths.
