Almost two years ago when the
first Floating Power Plymouth car

In this price field new features.
Among these were, Of course, Floating
Power motor mountings. the first
fundamental improvement In motor
cars since the closed body. Equally
important was the full-size, roomy
ard comfortable body with smart,
iacy lines. Free wheeling. double
drop frame and easy-shift silent sec
ond transmission were just q few Of
the features which the first Floating
Power Plymouth introduced to low
priced cars.
Just Is this car set the pace
which was followed in swifter fashion
by the new, finer Plymouth of 1892

ing among 1899 low priced motor cars.
Entirely new from bumper to

similarly concealed gasoline tank and
sloping hood louvres carrying out the

sedan, and convertible coupe.
Has 70 Horsepower
The new Plymouth Six offers for
the first time, q six-cylinder Floating
Power engine in the lowest price field.
The new engine is mounted in rubber
IL two points and has bore Of 3h
inches and stroke Of ~ inches
with total displacement OF 1898 cubic
inches, developing 70 brake horse
power at 5000 revolutions per min
ute.
A downdraft carburetor Of Chrysler
Motors design Is largely responsible
for the very favorable ratio between
power output and piston displace-
raent as well rs the fuel economy.
The latest perfected type combine
ton air cleaner and intake Silencer
assures further perfection Of engine
performance. An automatic thermal
control has been built into the mani
fold.
Fuel Is supplied to the carburetor
Dy a diaphragm type fuel pump. An
even fuel pressure, regardless Of
throttle opening. is maintained by an
air dome on the fuel pump.
Intake valves are Of chrome nickel
steel and exhaust valves Of heat re-
sistlng silchrome. To overcome the
destructive heat Of the exhaust flame.
special exhaust valve seats Of Z
tungsten-chrome alloy have been in
serted In the cylinder block.
Particular care has been exercised
In grinding the camshaft. Cam COM
tours are such that the valves are
raised and lowered with very little
perceptible noise.

close grained grey iron alloy. pro-
duced IN the foundries OF Chrysler
Motors. The cylinder walls are
brought to q mirror-like finish BY
two boring and two roaming OPERA
tons, followed by double honina.
Large water jackets dispose Of heat
quickly. Heavy ribs support the
crankshaft bearings and prevent dis
tortion IN the casting. Compression
ratio Of SIS to l Is standard with
"Redhead" compression ratio Of 81
to Is optional at slight extra cost,
The crankshaft Is liberal Ia sise
and Is supported BY four bearings ~
inches IN diameter. Bearing loads
are reduced BY counterweights forged
integrally with the crankshaft, Steel
back interchangeable bearings Of thu
precision type are used. ii
