How To Rebuild Your Ford V-8 351C-351M-400-429-460.pdf - Index of

12-15 ft. lbs. 4291460 has a horizontal
bolt pattern. With its gasket in place on
the pump, moly on the arm and one bolt
in hand and the other in reach, locate the
pump in position and secure it by
threading the bolts in. Tighten the bolts,
then torque them 20-24 ft. Ibs.
Carburetor-Carburetors have varied widely
since 1968, from the performanceoriented
351C Boss and HO and the
429CJs and SCJs to the current emissionslmileage
tuned carburetors. Also,
some do and some don't use carburetor
spacers. There are so many combinations
that being specific would be too complex,
however they are generally the same except
for hookups for the various emissions-related
devices, both on and off the
carburetor. There are also considerable
differences in carburetor spacers, from
those which insulate the carburetor base
to those that recirculate exhaust gas back
through the induction system. Spacers
vary from a thin stainless-steel plate to an
aluminum spacer with an EGR (exhaust
gas recirculating) valve attached. The
order of installation from the carburetor
up is gasket, spacer, gasket, then the
carburetor.
Carburetor spacers don't present any
particular problem except for one, and it
can be a big problem. The one I'm referring
to is the aluminum spacer/EGR
valve. The aluminum eventually burns out
from the hot exhaust gases, resulting in
exhaust noises coming from the carburetor!
Check yours closely for signs of
burning out, then replace it if it appears
to have started. As a result of the burnout
problem, this spacer was changed to cast
iron as have all the replacement spacers.
A new one from your Ford dealer should
be cast iron.
With the gaskets, spacer and studs on
the intake manifold, add the carburetor.
Before installing the 4 hold-down nuts,
connect the choke-heat tube. Thread the
nuts on their studs and tighten each one
a little at a time until all are at the correct
torque-don't exceed 15 ft.lbs. The nuts
are easily stripped and progressively
tightening them eliminates the possiblity
of breaking a flange off the carburetor.
As you can tell by the number of parts
laying around, you can install a few more
before your engine is in the engine compartment-some
will have to be. Let's get
on with the actual installation. ~ost-of
the remaining parts and components
are easier to install just prior to the time
your engine is ready to be dropped into
place-while the engine is hanging in
mid-air.
Ford does a landmark business with these
aluminum EGR spacer plates. They burn out
with great regularity. This one is also plugged
up with carbon, so it didn't work anyway.
Inspect yours for signs of burning and
replace It If It looks bad.
With gasket or spacer and gaskets in place,
set your carburetor onto intake manifold.
Attach choke heat tube to choke before
securing carburetor, otherwise you'll have
a problem connecting the heat tube.
Install choke heater before carburetor.
351C is unique in that two center, right
mahifold bolts also retain outboard side of
heater plate. This was changed because
many attempts were made at removing
manifolds with these bolts in place as you
can see on page 41.
Tighten carburetor nuts with care. Don't
exceed 15 ft.lbs.
