34 manifold to stock 32 engine
 

Changing the manifold on my stock 32 original engine to a 34 so that I can
run a 2 barrel carb and a better fuel pump.
Question; I bought a new fuel pump rod described as for all V-8's with an
aluminum manifold that is 7.87 inches long. It appears to be too short. My
original push rod is about 8 3/8 inches and looks like a better fit.
What should I be using ?
Thanks for your help with this conversion.

OK...dimensions in my head are VERY rough, but there are only 2 heights to choose from.
Manifolds using the 7.87 rod are somewhat more than 1" high at the very back from block deck to platform for pump stand. Those using the 8.87 rod are 1" more. These are the only rods in the book for '34-48. Dividing them by aluminum versus iron is a generalization that is not always correct.

First remember you are going to also need a new generator. Next be sure to check clearance with the fan and hoses. I think the '34 manifold will put the generator too high. I think you need a '37 manifold (contact me if you need one) that puts the generator lower.

Charlie,
Thanks, but I have a 36 manifold which, as mentioned, has the mounting surface 1" lower than the 34. The 36 manifold has the same generator height mounting as the 34, by the way.
I want to use the 34 manifold as it has the same base design as the 32.
It sounds as if I need the 8.87" high push rod as called for iron manifolds ??
I have seen several 32 engines which use the 34 manifold, so there must be a simple solution.

There were two aluminum intake manifolds from two different Ford suppliers and these manifolds had different heights from the cylinder block to the fuel pump stand hence the different push rod lengths. The cast iron reference is a red herring and should be ignored for your purposes.

Re: 34 manifold to stock 32 engine
 

These are 34 intakes .
Note the hole for the fuel pump stand . It is diamond shaped . This intake takes a LONG pushrod . Also note the fuel pump stand - it is straight on the backside .

There is an early 35 intake that looks like this but it has a round hole for the vented block tube .

Re: 34 manifold to stock 32 engine
 

I would recommend using a 37 intake on a 32 engine if it's installed in a 32. The original 32 intake mounts the generator down low, as does the 37 intake. This positions the fan blades low enough to clear the radiator tank and still will allow adjustment as the belt wears. Use the appropriate length fuel pump push rod, and generator.

Just for reference this is a photo of the early 35 intake.

Re: 34 manifold to stock 32 engine
 

Anybody have photos of a aluminum 37 manifold that mounts the generator lower than the 34 through 36 ?

Re: 34 manifold to stock 32 engine
 

Just happened to have some pictures handy :). This one is for sale on an ad I have listed here in swap for sale section.

ps...I removed most of the studs on this intake manifold to use on another intake I was setting up. Those missing studs will be replaced if/when sold.

Below are photos of the two '34 manifolds (40-6519-B and 40-6519-B2) that I mention above. Both take the longer fuel pump push rod. The pdf of the period Ford of Canada Service Bulletin covers the six basic intake manifolds used on the '32-'35 V-8s and height differences for the fuel pump base.

David ,

If I have ever seen the second type I must have dismissed it as 35-up .

The diamond shaped FP stand hole is a sure giveaway . Learn sumpin evva day !! .

Was type 2 used in the US ?

Odd that there is an early 35 manifold that looks like the normal 34 ??????


ADDING pics of manifolds 40-6520 AND 40-6520-1 . Different deal but the iron one seems uncommon also .

Re: 34 manifold to stock 32 engine
 

David,

I believe it was used in the U.S. as the part number is not uniquely Canadian (i.e. 40C-6519-B2 instead of 40-6519-B2).

Re: 34 manifold to stock 32 engine
 

Looks like you need to get that engine out of that damp dungeon you have it in!

Re: 34 manifold to stock 32 engine
 

David: I have never seen the 40-6519-B Light Design. Thank You for the Canadian Service Bulletin.

Damp dungeon ?

Thatz me bacement Rocky !!!! Notice the cement blocks are neither wet nor stained .

Now the manifold rescued from a fencerow trucks engine was damp for many years and shows it but it did not get that way where it is .

So no need to worry about that motor - it is very happy where it is with numerous other siblings .

I'm with Terry as I have never seen that manifold either .

Re: 34 manifold to stock 32 engine
 

To add to the story, that manifold was on the engine of a low-mileage early '35 phaeton (U.S. manufactured) that I'm the second owner of. Obviously there's no way of knowing that it is original to the car, but the engine did still have its standard cylinder bore.

Regarding Canadian Service Bulletins, at least for the 1932-39 period, they consistently have more articles and more illustrations than the U.S. versions month by month and are a great source of information. The Canadian parts catalogues also often have more content than their U.S. counterparts. The merging of the hardware and body parts catalogues for the '35s and '36s are good examples.

Re: 34 manifold to stock 32 engine
 

The 40-6519-B and 40-6519-B2 manifolds appear to be quite different in basic design. The 40-6519-B is a log type (or 360 degree) manifold. The 40-6519-B2 is of the 180 degree design with the flow separated into two distinct flow streams, each feeding four cylinders. All of the later manifolds were of this type of design. There might be a significant performance difference in the two designs under certain conditions.

Not so...both styles are indeed dual plane, ie, 180* type manifolds
