Changing a Flathead manifold is relatively
simple as the cooling and ignition systems aren’t disturbed. The hard part is
getting the gasket surfaces perfectly clean.

Triple carbs on a Flathead mean the
generator has to be moved off to one side. Brackets are available for left- and
right- side mounting. Installation does require longer head studs.

With the gasket installed, the manifold was
dropped in place. Note only the center carburetor has a choke.

This is a cool trick to allow use of the
stock mechanical fuel pump. To gain the necessary clearance with the new
manifold and carbs the deep Ford sediment bowl/filter was replaced by a
shallower assembly off of a Mopar fuel pump.

Speaking of stock fuel pumps, there are
three different pushrods, 7-7/8 and 8-7/8 inches, for '32-48 engines (usually
aluminum manifolds use the short one, cast-iron the longer) and 10-1/16 inches
for '49-53.

Edelbrock offers progressive linkage that
uses the center carb only until half throttle, with all reaching wide open
together. In this case solid linkage operates the trio together.

Edelbrock has reintroduced their vintage
cast-aluminum fuel blocks for dual, triple, and quad carb applications. These
fuel blocks feature a single 3/8-inch inlet and two, three, or four 1/4-inch
outlets. They're available in satin or polished finish.

Fuel pressure should not be more than 3
psi. If other than a stock Flathead fuel pump is used a fuel pressure regulator
is necessary. Edelbrock offers a regulator (PN 1789) that is adjustable from 1
to 4 psi.

pressure should not be more than 3 psi.
The Uni-Syn provides a visual method of
balancing multiple two- barrel carburetors. The throttle blades are adjusted
until the ball in the sight glass is in the same spot when checking all the
carbs.

The Edelbrock carburetor has a
zinc-dichromate coating for durability and an extended throttle shaft to make
connecting multiple carburetors easy.
The fuel inlet system features a 3/8-inch
hose fitting, a center hung float, and a needle with a Viton tip for long life.

Access to change jets is through two
removable plugs in the front of the fuel bowl. To the left of the screwdriver
is the top of the power valve.

Accelerator pump cups are made of a special
blue material that prevents rapid deterioration with today's gas additives.

This is the vacuum side of the power valve.
When the vacuum drops to a certain point it opens to add more fuel. Stamped
with their rating, a 45 stamp means the valve opens at 4.5 in/Hg, an 80 means
the valve opens at 8.0 in/Hg.
