BIG FOUR-BARREL<br />
CARBURETOR<br />
The <strong>1954</strong> <strong>Cadillac</strong> engine is<br />
equipped with a four-barrel<br />
carburetor which provides remarkable<br />
advantages in performance<br />
and economy. In<br />
combination with <strong>Cadillac</strong>'s<br />
unrestricted intake and dualexhaust<br />
manifolding, it plays<br />
an important part in the highpower<br />
output of the <strong>1954</strong> engine.<br />
The <strong>Cadillac</strong> four-barrel carburetor works as two sets of<br />
dual-barrel carburetors mounted on the engine in tandem.<br />
The forward dual-barrel unit is the basic operating or<br />
"primary" carburetor. The aft dual-barrel unit is the<br />
"booster" or "secondary" carburetor, and comes into play<br />
as needed. At all cruising speeds the engine works with<br />
maximum economy from the primary carburetor. But, when<br />
rapid acceleration is desired, simply depressing the accelerator<br />
pedal brings the "secondary" dual-downdraft carburetor<br />
into operation. This means that more air rushing<br />
down the four barrels creates greater pressure in the intake<br />
manifold. This pressure forces more air-fuel mixture into<br />
the cylinders for maximum power and amazing acceleration.
