Down Draft Intake Manifold Info
Anyone have any idea what this manifold was intended for when new. I don't believe Model A due to the port shape. I know what the carb is from, and dont know if that's a clue or not. My only guess is Iron Duke Chevrolet.

Re: Down Draft Intake Manifold Info
The slotted mounting ears look just like a Model A, B or C, but unless the posts are round (they don't look round in pictures), it probably isn't Ford.

Re: Down Draft Intake Manifold Info
Looks like a special built for T with the ports enlarged. If it were a factory produced part for some other application there would likely be one or even several casting part numbers, patent dates, etc…

Re: Down Draft Intake Manifold Info
Used one, not the best flow, and can ice up something fierce. Ported block to match. Ran it with a 1 5/8 Master carb with the air screw removed, Giant head and a custom Crower ground A cam (later learned it is a stock grind from an MGA). Set up Fouled plugs like it was protesting CARB. That said, gave power well past 80 mph w/3.63's and a warford. The things we learn!

Re: Down Draft Intake Manifold Info
Steve, It's made to fit a Model T, I have one too, mine is pretty old. I believe it was originally intended as an updraft. Horizontal ports were used in T blocks back in the day. Photo of is the Ed Winfield engine, not mine !

Re: Down Draft Intake Manifold Info
I made variations of this over the last 40 years. My earliest version utilized a Corvair Turbo. Unfortunately I had installed a quite “radical” camshaft and the car had a terrible low speed performance! I have continued to make variations of this design but I now divide it for about 6” of the flow length and then I can use a quite radical camshaft.
Just my experience
