Matched set BG 850 Holley Blower carbs

[Airpacker]

Boost referenced Holley 850's by Barry Grant.
Come with both original and chrome float bowls.
I got them as part of a package with a blower and have no use for them.
No idea what jets or PV's are in them. Never took them out of the boxes they arrived in.
They appear to be in good condition but I do not know their history.

$ 400 the pair plus shipping.

PM any questions.

What's involved in setting them up for normally aspirated twins?
Thanks,

Interested. What are the part numbers?

Also would like to know the #'s on the side of the carbs. I have some Holley 750's by Barry Grant that I need to sell before I purchase 850's.

Thanks

Thet are 4781's with the choke horns milled off. At least that is the number engraved into the main carb body.

Do you know the Barry Grant part number?

 

[Airpacker]

there is a 2723A and a 2723B stamped into the airhorn on each carb?

other than that, I have no idea what a BG part number would look loike or where to look for it.

I don't belive you can find a BG part # for them anymore without calling BG. You have to use the Holley numbers engraved on the side. Mine have BG CNC'd on them. My 750's are on my 590HP 454's

Airpacker I will get back to you after I work out some details with Boss252
