Identifying 5200s

[Anonymous]

I have searched the archives, but I'm still a little unclear on the differences between the weber 5200s and the 32/36 holley-weber. I'm just trying to buy the one that will be best for my application:
200 with FSPP headers and otherwise stock

I realize I will have to get the clifford or stovebolt converter and probably different jet sizes.

Here are three I found on ebay. Can someone help identify any differences and predict the CFM ratings?

What about the ones from Stovebolt?
Any guidance would be appreciated.

Basically, they are the same carbs. They were originally designed and manufactured in Italy by Weber (Model 32/36 DFAV). Later they were manufactured by Holley (Model 5200). They were made in a bunch of versions. Some had traditional fuel metering, some had electronic, some had a hot water choke, and some had electric. Plus, there were at least 10 different throttle linkages. Most had a 270CFM factory rating, but there were some made that were rated at 235CFM.

The ones in those adds all looked to be the hot water choke versions, although the middle one appears to be missing part of the choke system.

I havent installed it yet, but I got mine from Stovebolt. I don't really like the linkage on the one that I have, but I think that it's pretty much pot luck on getting a particular linkage. Another user TheDude got his from stovebolt, and his has a different linkage from mine.

One issue with the 5200's is mounting the air cleaner. The air filters on these carbe have a unique mounting system. They have 4 bolts at the corners rather that a center bolt like most carbs. Plus, they have an odd oval shape that requires an adapter plate to mount a standard air cleaner.

Despite the claims and counter claims, all Holley Weber 5200's and Weber DGV series 32/36 were the same. These are early Pinto 2.0 carbs. After the nast speight of under bonnet fires, they got US made carbs with proper fittings, not the suspect early build of the Bressel units.

When the 2.3 engine arrived in 1975, they got a US made carb. The carbs flow the same. They are 227 cfm at 2" Hg pressure drop, and 278 cfm at 3"Hg.

Later, Chrylser (2.2 Omni/K-car) and Chevrolet (Vega) used DFV variants with another 5000 series or 6000 series number. The positions of the main and secondary circuits reversed to suit the application, basically copies of the Weber's water heated choke DFAV or Electric choke DFEV.

Although similar, they are not the same, but are Holley Weber carbs, made in the US. Again, they are claimed to have different cfm ratings, but are in fact the same cfm at 2" or 3"Hg.

Basically, the Pinto 2.0/ 2.3Mustang II, 2.3 Fox Mustang carb was Weber carb was made by either Bressel, Weber themselves, or Holley in America after 1974.

Their were 3 changes to the DGV series.

All US carbs had no fuel return line. There was the box stock DGV, but there were also water heated choke DGAV) and electric choke (DGEV) vesions overseas, and all foriegn carbs had bleed back fuel lines to the fuel tank to improve hot fuel handling. Your US market carbs never got that blead back feature, but did have various kinds of choke and emissions gear variations. All were called the 5200, and just got another Holley Weber line reference number.

All ran the same 1.02" and 1.06" venturis and 1.26" and 1.42" throttles

It looks like the links you provided are the style I would suggest for a couple of reasons.

These two reason make a big difference in which of the three are best for adapting to our 200 applications. First off select the style that sports the left hand primary. This location is nearly identical to the stock position and requires vary little modification to the stock length of the linkage rod. Second inspect the left hand primary shaft. I believe the 5200’s have the nut on the throttle shaft in the back. What happens if you would like to use a different lever on the linkage side of the carb? Find the 32/36 DFV. The primary shaft is on the left and the linkage nut is on the linkage side.

Have fun, Ric.
