Not sure if #8050B is an actual Holley #. There is a #80508; 4160 series 750cfm vacuum secondary. Do you happen to have a picture?

On the choke horn there is a list number. Give us the list number and someone with a Holley book will look it up and tell you what it is.

Yea, that air horn info is what you need.

The first line is a '69 Ford part number, which means Holley provided it to
Ford as OEM part. C9ZF-9510-J is listed as 1970 Ford H.O. Street 302
Std. 780cfm Emission. List R-4511A, model 4150, front metering block
6211, rear 6213. That's a '69 Boss302 carb!

The second line is the Holley list number, which is the reference you
use to look up by Holley part number. The Ford application reference and
the stamping on the air horn seem to agree it's a List 4511. I couldn't
find the 4511 details in the limited listing I have.

The last line is a 3 digit encoding of the manufacture date. 0=1970,
2=February, 1=first week.

[Oops, just realized that's not a picture of the air horn for br0nc0xrapt0r.
Thought he had a cool find there for a minute. Oh well, someone has a
Boss302 carb.]

You can get all the info on rebuilt kit#, factory jet sizes, power valve,
accelerator pump, secondary spring, yada yada yada using the List# and
the Holley Carb Numerical Listing:
http://holley.com/data/TechService/Technical/Carb Numerical Listing.pdf

BTW, the Holley 4 digit date coding indicates 258th day of the year (some time in
September) and year ends in '6' ('76/'86'/'96/'06). I'm not sure if that style of
carb was available in '86, so it's probably a '96 if reasonably used or 2006 if pretty
much new.
