In looking for an intake manifold for my 1923 touring I find quite a variety of markings. Here are six out of the pile.


All the marks are oriented the same way in the picture, but they're in two directions on the manifolds. In other words, the marks on the top row would be upside down as the manifold is installed on the car.

Here are the close-ups:


Top left


Top center


Top right


Bottom left


Bottom center


Bottom right (no mark at all)

So here's the question. Do the marks and/or their orientation have anything to do with year(s)? If so, what's right for 1923?

Take your choice, I would use the prettiest one.

Steve, I think those are mold makers marks. That way the can keep track on how many he made and if there is a problem they know who made the part. Or what mold is being used. Nothing about the date, Scott

I would suggest using one with the Ford in script, if you have one, as most parts were identified as such starting in the early 20's.

If you don't have one, I can send you one for the price of postage.

Steve, stick your finger up the carb end and use the one with the biggest hole.

You could also fill them up with fluids and find out what give you the most volume.

Well, this is a bit of a surprise. According to the MTFCI guidelines, the Ford script on the intake manifold first appeared in 1919. Apparently eighteen of the twenty manifolds I've found here are 1914-1918. Of the two I have which do have the script, one has a petcock stuck in it and is the one I'm replacing with one that hasn't been modified. I have no idea how it came to be that 90% of my manifolds are the earlier type.

Here are two photos of the intake manifold on Betsy, my January 1924 build cut-off touring car.

Steve,

Did Western Auto Supply have a place in Kansas? It was claimed by them that by 1920 you could build a whole Ford from their catalog with parts never touched by a Ford employee or having seen the inside of a Ford shop. It is said that the reason Ford started scripting was that was the only legal way to prove a genuine Ford part.

Most guys want to poo poo the WesternAuto influence...but good old George did make millions duping parts for T's! Somewhere in your past you have a Pepperdine connection, yes??

As to what to do with your 'pick'...biggest bore or volume...smoothest inside surface is your best bet

Strictly an observation.
I would say the majority of probably several bushels of common iron intakes I have had through the years did NOT have a Ford script.

George, the answer is yes. Pepperdine College, 1964 grad. That was before they moved out to Mailbu and became a big fancy university.


The school colors are blue & orange. Quite a coincidence, eh?

Steve, if you are really lucky, you may find a cast iron manifold the same as the higher volume 13-14 models. These are most desireable.

Our 26 Coupe has a "Ford" and a "G" if anyone is taking notes.
