The Carl's Ford Parts, Branda Performance and the FE Forum would be good places to check for BJ & BK carbs, but eBay may be a more common place to look. I don't see a lot of these 2 X 4V Carbs come up for sale on eBay too often, but when they do they never seem to be cheap, nor do they ever seem to be in very decent shape. Oddly enough there are several of these BJ, BK Carbs on eBay right now.

As you know their full Ford part numbers are C3AF-9510-BJ (Holley List # 2805) for the front 4V Carb without the choke plate and C3AF-9510-BK (Holley List # 2804) for the rear 4V Carb, with the choke plate.

As most people know the C3 in the Ford part number stands for 1963 since the first factory Ford application for these 2 X 4V BJ, BK Carbs was on the 427 FE engine in 1963. These carbs were used for a factory Ford application again the 1964 Model Year and then again in 1967 the BJ, BK Carbs were used in 1967 on the Shelby Mustang GT500.

shelbynut, as you know any of these used BJ, BK Carbs can easily show-up having a separate manufacturing date code being from 1963, 1964, 1965, 1966, or 1967. Since your application is a 1967 Shelby GT500 are you looking for a 1966 dated matching set or a 1967 dated matching set?

Oddly enough go check out seller:  freedomagain2012 on eBay. He has several BJ, BK Carbs currently on eBay. He has one BJ dated 382, and four BK Carbs dated 402, 601, 601, and 632.

The only other BJ Carb I currently see on eBay is by seller: mikesclassiccars which has a 1964 date code of 482.

As a note of caution for anyone looking to buy a used Carburetor at a swap meet or over the internet, know what you are looking for!!!!! A Holley 4V has a part number on the main body, numbers on the metering plates, and on the base plate. Old 4V Carbs got used, abused and modified by many a drag racer and some parts like base plates and metering plates have been switched. Just because the part number or Holley List number is what you are looking for on the main body, make sure both metering plates and the base plate are correct and matching too. Expect any used carb to need a rebuild. Anyone can rebuild any old Holley, Autolite, or Motorcraft Carb. Even you can do it! However its much better to have a good Carburetor rebuilder already lined-up. Don't expect a good carb guy to be cheap either. If you want "cheap" rebuild it yourself. If you want it "good and done right" send it to an expert rebuilder. Not all good rebuilders replate a Holley Carb to its original color. Make sure who you are going with does what you are looking for. Personally, I want a part number and date code correct Carb that just works right for my application. Others want the whole 10 yards with the correct coloring and ink stamps. Make sure who does your rebuild is going to give you what you want.

When buying a used 4V Carb, get one without any missing or broken parts and make sure the linkages and shafts are not frozen in place. It was a common racing trick in the 1960s and 1970s to remove the choke plate to increase air flow on a race car engine. In worst cases some carbs had the whole choke horn completely ground off the main bodies. Its not uncommon to find otherwise good used carbs missing their choke plates. Some missing or incorrect pieces can be easily replaced, other missing or switched out pieces will be very expensive or impossible to replace. Know what you are getting.

A lot of old Carbs from the 1960s and 1970s have been sitting on a shelf somewhere and haven't been on a car in decades and can be in pretty decent and easily rebuildable condition. Other Carbs can look like they are corroded pretty bad. If the main pivot shafts for the butterflies on the base plate are frozen it may or may not be possible to soak them overnight and get them freeded-up. However, in many cases they won't loosen up then the base plate is junk. If an old used Carb looks corroded and/or the main pivot shafts are frozen I don't recommend wasting good money on it. If it looks like scrap its only worth a scrap metal price, regardless what part numbers and date codes are on it. A lot of these rare muscle car carbs are being reissued by Holley. Its a lot better idea to buy a new reissued Carb than it is to waste money and time on corroded junk.

Starting on page 18 in the September 2019 issue of Car Craft (currently on the news stands) there's a great article on tuning tips for the Ford FE Dual Quad 8V induction system. For those that are interested grab a copy of Sept. Car Craft while its still available. This article is general enough to apply to any dual 4V for intake system and its worth getting for a reference. This Car Craft article even has a in-car picture of a BOSS 302 race engine with the Dual-Dominator set-up. Carl's Ford Parts is mentioned in the article and listed at the end as a reference.

Check this out:

That's a pretty good deal, I paid Carls over $1000 in 2005 and when he gets them back in stock they will be over $1500
