and the accelerator pump connector rod in the
middle stroke hole in the throttle lever, and the

The Chrysler FirePower engines arc equipped
with 4-barrcl downdraft Carter carburetor Mod -
el WCFB-2314S. Basically this new carburetor
is the same as the 4-barrel carburetor used on
the 1955 Chrysler FirePower engines wit h the
exception that the throttle lever, flex spring
arm, and flex dog have been changed and a
throttle flex spring stop has been added (Figs.
6 and 7). These changes were incorporated to
effect smoother
carburetor operation.
With the exception of a change in the method
of
adjusting the carburetor throttle linkage all
other service procedures can be found in your
1955
Chrysler Shop Manual, D-15431.
Throttle Linkag e Adi us tment
(1) With primary throttle valves in wide open
position, bend the
throttle operating link
(A) (Fig. 6), so thal the secondary th rottle
valves
are open 10 degrees.
(2) Bend the
throttle shaft dog arm (B) so
that the seco ndar y throttle valves start to
open when
the primary throttle valves are
open 40 degrees.
57
(3) With operations 1 and 2 completed in the
above order, bend
the flex sp ring arm (C)
to give positive tension
on flex spring dur-
ing last 5 degrees (Maximu m), of primary
throttle valves before closed position.
EXHAUST SYSTEM
The exhaust system for the 1956 Chrysler cars
remain fundamentally the sam e as the 1955
Chrysler Cars with the following changes.
The Spitfire Engine
exhaust pipe and "Y"
pipe are a sing le assembly extending from the
manifolds to the muffler elimin
ating the short
extension pipe.
On the FirePower Engine - (dua l exhaust
system) the exhaust pipes will extend from the
manifold to the mumer, eliminating the
sho rt
exhaust pipe extension. The tail pipes are a
new design; the exhaust stream is directed to-
ward the ground instead of directly aft.
On all models, the exhaust pipe is clamped
to
the muffler rather than welded. The exhaust
pipe to transmission steady rest bracket has
been eliminated. it is
therefore importan t that
the muffler be sufficiently supported before dis-
con necting the exhaust pipes fr om the exhaust
manifolds: A new tuil pipe rear bracket attach-
ing the pipes to the side rail s has been added.
MANIFOLD HEAT CONTROL VALVE
The exh aust pipe flange pilot and the pilot on
the heat control valve have been removed; elim-
inating the counterbores in the exhaust man-
ifold and heat control valve.
NOTE: The heat cont1·ol valve must be installed
with the
countenveight toward the front of the
engine.
This will place lhe small anti-rattle
spring 1·etaining
pin tou; a1"d the rem· and ad j a-
cent to the cyh"ndel· block.
GASKETS
New steel gaske ts with a bead used for sealin~
(similar to cylinder head gasket const ruc tion)
will be used
at the intake manifold. exhaust
manifolds, and at the exhaust manifold flanges.
