Anyone recognize this:

Rob;

That's listed as a "generic" OTC HP carb designed for the 396 Chevy.

Hope this helps.

Holley had a handfull of OTC carbs designed for BBC's, but I've never personally tested one to see if they were any better than the OEM carbs. (I do have an old 3977 S carb in my core pile that's listed as "Ford & Chevy, 426 Eng. (High Perf. Only)" that I might try sometime down the road.)

I can say that the original 3310EH (396/375) style carbs are still one of the best all-around street carbs Holley ever produced. I've ran them on everything from 327's to 454's, and they worked very well.

Do you have something you plan to run this carb on? I'd be interested to see how well it works if you do.

If nothing else, these obscure carbs make for neat conversation pieces. [img]/ubbthreads/images/graemlins/smile.gif[/img]

Well, a pure stock buddy of mine bought an inatke for a 427 Ford that had a duo of these carbs mounted on it, and he was curious if there was any demand or value in these carbs. Just curious, are these 780cfm units?

Rob;

I'm not sure on the cfm ratings as my Holley performance catalog doesn't cover this carb in detail; however, my IPS Holley catalog does show that it takes 172 primary and 173 secondary throttle blades, which are 1 11/16". Can you find out what size the venturi diamaters are (primary and secondary, they may be different) and what style of boosters they have? That will give a fairly good indication of the cfm of these carbs.

The IPS catalog does show it as being a 4160 style carb (secondary metering plate instead of a block), the primary block being a #5812, and a secondary plate #34R-2007-31.

As far as demand or market value, I'm not sure; I could check around tomorrow and see if I can find anymore info on them if you'd like.

HTH
