| Hi Bill,
I made one up yesterday from a 4” PVC cap. The ID to fir the 3447 is just 4.25”. Since the cap was just a bit larger, I used a strip thick walled vinyl tape around its inside perimeter to take up the little bit of slack. Now just waiting for my vacuum gauge to arrive.

The original poster says he has 3447 carbs, which have the smaller AFB air horn compared to the 3705 and any newer AFB, all AVS, and all Edelbrock. Just looking at Jegs etc I didn't see any to fit the smaller air horn, which is what I would need too. I'm considering getting one of these put together based on the great info provided in this thread, but unless someone has a source for a hat for 3447, one would have to add a big-to-small adapter under the hat, under the synchro assembly. Oh well I probably have one stashed somewhere. Bill & Kathi Parker, South Central Indiana You can buy a cheap carb bonnet and Edelbrock synchronizer and mate them together easily to work. You have to disconnect the carb linkage and only adjust the idles to match vacuums one at a time. It works miracles!
Here that video from Shepherds Garage
Yes it really works well. Great tuning tool David! Originally made by Edelbrock as well but without the carb hat…I believe I have one of the original Edelbrock “Uni-Syn” carb synchronizers in my parts stash somewhere. ![]()
Gary P. I use the Dvorak 4 barrel carb synchronizer on my 1962 Dodge Polara 500 Crossram. They take the single carb motorcycle synchronizer and attach it to a housing that fits over a 4 barrel. Click on this link: https://www.dvorakmachine.com/ I got mine from Dvorak 6 years ago for $99. Without synchronizing the Crossram carbs the engine will not run properly. If I can find the old video on YouTube of how to use it I will provide that too. --
