number of improvements that
will enhance the comfort and safe
ty of driving, major interest in the
chassis story is found in the great
est variety of power plants ever
produced by a low price car build
err.
Offered in the line that makes its
bow at dealer showrooms Friday,
October 10, are one six and
four eight-cylinder engines, rang
ing in horsepower from 140 to 283.
The six develops 140 horsepower.
The Fights. range in horsepower
from 2s3, 27O, $50 and 245 for the
Corvette VS" to 220 for the
Super Turbo-Fire $685." 1876 for
the Turbo-Fire $685." and 1872
horsepower for the Turbo-Fire
1895"
Each of the engines is improved
mechanically, but the gain in pow
er-up from a peak of 225 horses
in the 1856 line-is primarily due
to larger bore, higher compression
ratios, higher lift camshafts and
fuel injection.
With displacements of the six
cylinder ond lowest cost Vs re-
naming unchanged at 235 and 265
cubic inches respectively, the more
powerful Fights are measured at
2S3. Bore has been increased one
eighth of an inch over the highest
powered 1856 V8 to new 1875
inches. Piston stroke in all Chevro-
let Fights stands at inches, one
of the shortest in the industry and
contributing factor in the effort
less power output.
All high performance engines
are based on the 283 cubic inch
block, while varying in fuel Undue
ton, compression ratio, camshafts
and valving. Mechanical-type valve
filters are used in the special high
performance engines with COM
preston up to 10.5 to 1 with fuel
injection. Full pressure lubrica-
ton to the valve litter galleries
replaces the former meter system
on all VS.. Full flow oil filters con-
tinue as a popular option. except
on engines equipped with two four
barrel carburetors or fuel injec-
ton. Here filters are standard.
There are numerous other refine
ments. Top deck of the vs. cylinder
block is increased in thickness for
improved cylinder head attach
ment. The re-design will minimize
cylinder wall distortion through
over-tightening of hold-down bolts.
Spark plug electrodes protrude
one-eighth inch farther into the
combustion chamber, resulting in
shorter flame travel. New metal
heat DETECTION shields between
spark plugs and exhaust manifold
protect the spark plug wires and
boots from heat. Starting motors
of both six and V8 have been modi-
fed to increase the efficiency of the
solenoid.
Improved engine breathing is
claimed for new "ram's horn" ex-
haust manifolds on the VS.. The
new design provides larger gas
passages which gradually increase
in cross-sectional area from the in
let port at the cylinder head to the
outlet. The manifolds are designed
to rush spent gases from each cyl
inder with, equal freedom from
back pressures.
A new distributor of advanced
design is used on V8 engines equip
ped with the two-barrel or single
four-barrel carburetors. This plac-
es the breaker points directly
above the shaft bearing, reducing
fluctuations in the gap setting. An
access door in the distributor cap
provides for the setting of the
breaker gap while the engine is
running.
Clutches on the 1857 Chevrolets
have been improved for durability.
Both nodded and woven facing ma
terial have greater strength and
wear resistance. A new semi-cen-
