I bought some junk and this short manifold was with it. It is factory made, with a threaded hole for vacuum. I wonder what it is good for?

Fording a low water bridge maybe?

Maybe it's for mounting your Stromberg OF a little bit higher so it soesn't hit the frame rail?

Could it be Maxwell? A lot of Maxwell parts are very close to T stuff.

Is that true that a Stromberg OF on a stock T manifold hits the frame rail?

I have an OF that I would like to try someday and would like to know if I should be looking for a different intake manifold to go with it.

Thanks!

Hi Mark,

You asked:
"Is that true that a Stromberg OF on a stock T manifold hits the frame rail? "

Well, yes and no.

With a stock iron manifold you will likely be okay.

With a stock aluminum manifold you will likely be okay.

The occasional problems have been encountered with the reproduction aluminum manifolds. Apparently some of them have an "off" angle milled at the port which tilts the manifold slightly closer to the frame rail. This is not a problem with a stock carb, but can cause trouble with a wider carb such as the Stromberg OF.

I have an OF with a reproduction aluminum manifold on my coupe and it IS real close but not touching the frame. Good luck with your project. Bill

Thanks, Bill. I have a stock iron manifold on my '24, so it sounds like I'll be OK when I decide to mount the OF. I'll be sure to check it, though. :-)

Typical wear marks that can be found on a Stromberg OF. Intake gasket thickness, frame distortion, might influence. Some OF's rub, others do not.

I have a Stromberg OF and a stock cast iron intake manifold. The OF had a slight interference with the frame just enough that it rubbed. What I did was machine the intake manifold flange where the carb. bolts to the manifold at a slight angle just enough to tilt the OF towards the engine and away from the frame and it worked fine.

You could probably just file the intake manifold to achieve this slight angle on the intake manifold flange also.

Accessory boat engine manifold? Would keep the carb up where it was more accessible and out of the bilge.

Here is a "period" frame notch someone made to clear a carburetor!

I had an OF or LF that I had to file a small notch in the frame for it to clear.

Tom
Maybe the connection is to run a vacuum windshield wiper?

The stubby manifold will raise the carburetor, compromising the gravity feed fuel system. The port in the manifold would provide a take-off point for a vacuum tank to draw fuel to the engine.

My 1924 Tarrant tourer with the fuel tank hanging under the spare tyre carrier has a vacuum tank to suck fuel to the front. The only problem with such a system is when confronted with a long steady pull, which results in low vacuum and fuel starvation. This is not such a problem with 3 and 4 speed transmissions where gear changes make for changes in vacuum during operation.
