A while back I posted pics of a of number of Ellis intakes. I finally found one for the 572 Overhead Continental that's in my 1946 260XW Brockway. I have the factory literature from Ellis and it notes that you are supposed to use (2) Ford 59A 9510A carbs (which I already have.) The problem is that the manifold has SAE (or size) #4 flanges on it, with a 1-15/16" hole and (2) 7/16-14 studs that are 3-5/16" on center. I also need to rotate the carbs 90 degrees so I bought a set of Offenhauser 3859 adapters that go from 3 holes carbs to a 2 hole carb with a 1-1/2" hole and (2) 3/8" studs that are 2-15/16" apart. I thought the would be enough material to modify them but there isn't. Does anyone know if the correct adapters are available or should I just make my own? Any help would be appreciated! Thanks, Tom
I remember buying a pile of NOS Ellis intake manifolds at the Maple Grove Drag-strip flea market many years ago. I had never heard of Ellis, and they made many manifolds, mostly for big trucks.
I have one for a small port 228-248-270 GMC for 1 single barrel carb. Aluminum with all the cooling fins.
I have some Ellis intakes mostly GMC. One is for the GMC bigger than the ones we like, 228-302. All that have carbs are Zenith single barrels. The one for the big GMC 361-451 has adapters that seem to be 2 3/4" on the intake and 3" on the carb. Just eye balling with a tape. 817 is was into them. My advice would be to cut the bottom off of your adapters and TIG on a plate that fits the manifold and clocks the carbs the way you want them.
I’ll probably never use it. Here’s a few photos. The BU makes me think butane but never heard of using it. There is a divider in it to even out the fuel. I also have a 2- single barrel Ellis for a large port 270. By tapering the 228-248-270 small port head you can get great velocity for performance and low end torque. I’ve done that on a few with positive results.
