1931 & 1932 intake manifolds

[Pete Phillips]

Does anyone know if the intake manifold is the same between 1931 and 1932 Buick 50-series engines? Have a guy who is asking for a 1931 50-series intake manifold, and I have several for 1932 50-series.

From the 1928-41 master parts book  part numbers are

Manifold intake

3.265 1240120 1931 50

3.265 1259587 1932 50

 

Manifold exhaust

3.601 1252989 1931 1932 50

 

So intake manifolds have different part numbers, but that does not mean they will not interchange.

Need photos from some one.

 

Exhaust manifolds are the same, so may be some hope

I believe only the engine bore changed in 1932.  So, the exhaust manifolds should interchange. 

However, the intake manifolds may be different if different carbs. were used.

In 1931 the Marvel heat riser that attaches to the bottom of the manifold is a 1  barrel affair with a Marvel T3 carburetor which is 1 barrel.   Then if I'm no mistaken in 32 they went to a 2 barrel, in fact I believe they went to the TD-2S carburetor and the matching heat riser that was used on 1931 60 series cars and the 31 60 is 2 barrel, I've got that car..  Pete- if the 32 manifold has 2 holes at the heat riser mounting the user would have to change to the carburetor and heat riser setup for 1932.  1931 60 series heat riser in picture 1, on the car with TD-2S on the car.

I check through the parts manual and the intake gaskets are different for early 31's, late 31's and also 1932.  Heat riser and carbs are also different as stated above.
