1800 single plane intake ona 1438?

[70spider]

Hello all,
My carb on the 1438 is in need of a rebuild. I have done alot of research reading multiple sources on line and on this forum and it appears it would be a waste of time to rebuild the old 26/34 DHSA (vacum advance). So apparently my solution is to get the 32/36 DFEV and the consensus opinion is it works best with the 1800 single plane intake. Has anyone done this on a 1438? From what I have read the 1800 intake has an extra water port, would this be a problem?
Any help would be appriciated.

The 1438 has an open plenum manifold like the 1800. The 1800 may flow a little better, but if your 1438 is stock, you may not see any benefits. However, you may need to slightly enlarge the inlet of the 1438 manifold at the primary side, as the stock carb has a 28mm primary, so the opening might be smaller than the 32mm opening of the DFEV's primary.

Thanks Csaba,
Also does anyone know what the difference is between a Weber 32/36 DFEV and a 32/36 DGEV? The reason I ask my son bought one for his Toyota but decided to retain his stock carb, so I can get it cheap .

Never mind on the DFV and DGV question I found my answer. If anyone else was curious I found this from ClassicInlines:
DGV Carbs
The 32/36 DGV Series carbs were designed to provide an economical performance carburetor that increases power, improves driveability, and offers better fuel economy over the stock OEM carburetors. The DGV progressive carburetors are pre-calibrated from the factory, and set to run on stock engines. If the engine has been upgraded or improved with other performance items, such as a camshaft or increase compression, they may need to be re-calibrated or re-jetted for some applications. The 32/36 DGV is a progressive carb, so only the primary barrel is used for low speed operation. The secondary barrel only opens when additional air flow is required, for wide open throttle or high speed operation. As a progressive style carburetor, it offers excellent throttle response and fuel economy, as well as high end power when it's needed. The DGV's are an excellent 2V carburetor to use on stock and/or mild performance engines, and they are a great replacement carb for worn out or hard to maintain factory one barrel carbs. If your concerned more with mileage, low end power, and do a lot of city driving, this is the carb for you.

DFV Carbs
The DFV Series carbs are exactly the same as the DGV Series, but they are a mirror image, with the primary and secondary barrel positions reversed in the carb body. As such the throttle lever in the DFV rotates in a clockwise motion, rather then counter-clockwise, which may help you out when it's time to install the linkage.

Did you ever end up going for that DGEV? I'm curious to know if you were able to make it work, because I'm in a similar situation to what you were in about a year ago!
