Engine:
Eight-cylinder, 340 HP,
overhead, 90 degrees V-type; bore 4.13",
stroke 4.0"; displacement 429 cu. in. Max.
torque 480 ft.-lbs. Engine mounted in rubber
at three points. Compression ratio 10.5 to 1.
Pistons:
Aluminium alloy, slipper-type to reduce
friction surfaces and permit nesting between
crankshaft counterweights. New top
compression ring inverted to pump oil upwards
rather than down, one wide oil ring with
expander; top compression ring
molybdenum-filled to minimize wear on
cylinder walls. Contoured piston head
increases turbulence for fast, complete
burning of fuel-air mixture.
Carburetor:
New Quadrajet four-barrel downdraft with
equalized manifold; mechanical fuel pump;
dry-type air filter; new automatic choke.
Lubrication:
Full-pressure. Full-flow oil filter standard.
Electrical System:
12-volt. 13-plate battery. High-capacity,
42-amp. generator (55 amp., air conditioned
cars).
Gasoline Tank Capacity:
Approximately 26 gallons. Eldorado
approximately 24 gallons.
Turbo Hydra-Matic:
Fully automatic, improved torque converter
type with variable stator Except Seventy-Five
models). Converter multiplies engine torque
for increased driving thrust to drive wheels
during acceleration in any gear (low,
intermediate or high).
Rear Axle:
Hypoid. Differential housing offset to
provide straight-line drive. Ratio is 2.94
with a 3.21 axle available (3.21 only on
Eldorado). The 3.21 axle is standard on all
air-conditioned models and the Seventy-Five
models. Available (except Eldorado) is the
controlled differential which directs power
to the rear wheel having better traction.
Front Suspension:
Spherical joint with Cadillac independent,
helical-coil-type springs. Rubber-mounted
strut rods and rubber bushings absorb impacts
and isolate road noise. (Torsion bar
suspension on Eldorado.
Rear Suspension:
Four-link drive. Rear springs are
helical-coil-type. Rubber bushings for
quieter, softer ride. (Single-leaf springs
with two horizontal and two vertical shock
absorbers on Eldorado.)
Brakes:
Cadillac power brakes with
self-adjusting shoes; finned front and
composite finned rear drums. Split hydraulic
master cylinder provides independent piston
and fluid reservoir for front and rear
brakes.
Parking Brake:
Serves as true auxiliary brake... will not
lock in position with engine running and car
in gear... can be operated as a foot
emergency brake while car is in motion.
Automatically releases when transmission is
in any drive range with engine running.
Steering:
Cadillac variable ratio power steering is
standard equipment (except Seventy-Five
models). Energy absorbing steering wheel and
column . Overall steering ratio of 16.7 to 1
(except 18.2 on Seventy-Five models and 16.3
on Eldorado) and 38.5 degrees turning angle
provides fast response and short turning
diameter.
Frame:
Perimeter frame is fully boxed in its entire
length with hidden bulkheads for additional
torsional rigidity. Eldorado has a frame
especially designed for its front wheel drive
and front and rear suspension systems.
Tires:
Low-pressure, 2-ply, tubeless, size 9.00 x 15
on all models except the Fleetwood
Seventy-Five, on which the size is 8.20 x 15,
4-ply. Black sidewalls are standard on all
models. White sidewalls may be selected on
all models.
Cornering Lights:
(standard equipment) On the side of front
fenders, activated by directional signal
lever when headlamp switch is on. Project a
beam of light from the side of the car, thus
illuminating roadside and road signs for
convenience at night.
Tread:
Front and rear, 62.5". (Eldorado 63.5",
front; 63", rear.)
Wheelbase:
129.5" (Fleetwood Sixty Special Sedan and
Brougham, 133"; Fleetwood Seventy-Five,
149.75"; Eldorado, 120".) Overall Length:
224" (Fleetwood Sixty Special Sedan and
Brougham, 227.5"; Fleetwood Seventy-Five,
244.5"; Eldorado, 221".)
