SIXTEEN CYLINDER
ENGINE
The 1938 Cadillac sixteen cylinder engine is the result
of several years' development by Cadillac engineers for
the purpose of making sixteen cylinder smoothness and
performance available to a great many more motorists.
To accomplish this purpose, a power plant has been
designed in which sixteen cylinders totaling 431 cubic
inches displacement require no greater hood length
than was required for the former V-12 engine. Also,
the new Sixteen engine, although much larger, is actually
lighter than the former V-12. Unusual compactness,
economical service and extreme durability have
been realized by the combination of a very short
stroke, a V-angle of 135 degrees and an enbloc casting
of cylinder banks and crankcase. Other unique features
of design are the disposition of dual engine accessories;
two dual downdraft carburetors, two manifold systems,
two distributors, two coils, two fuel pumps, two water
pumps, two fan belts. Each bank of eight cylinders is
in running balance, hence the new Sixteen engine will
operate more smoothly on one bank of cylinders than
most eight cylinder automobiles.
The bore is 3¼ inches, the stroke 3¾ inches.
