1970 Chevrolet Nova SS 396 �€" Big Block 4-Speed with Cowl
Induction Why This Car Is Special The 1970 Chevrolet Nova SS 396
occupies a specific and well-earned place in the muscle car era.
While the Chevelle and Camaro got most of the press, Chevrolet
engineers understood that dropping a big block into a lighter,
smaller body produced a very different kind of performance car �€"
one that was harder to dismiss at the strip and easier to park
anywhere else. The Nova's X-body platform weighed significantly
less than the Chevelle's A-body, which meant the 396 cubic inch
Turbo-Jet V8 had considerably less mass to motivate. The result was
a car that ran quicker than its sticker price suggested and
competed directly with machinery costing far more. The VIN on this
car decodes to confirm it was built at the Willow Run, Michigan
assembly plant in 1970, with the SS package and the 396 engine as
factory-installed equipment. The engine code points to the L78
specification �€" the 375 horsepower version of the 396 �€" which
was the most powerful naturally aspirated big block offered in the
Nova SS that year. Chevrolet offered the 396 in the Nova SS in
three states of tune for 1970: 350 hp, 375 hp, and a solid-lifter
375 hp version. The 375 hp hydraulic-lifter L78 that lives in this
car is the high-output variant most buyers were after, rated at 415
lb-ft of torque. It is paired with the close-ratio 4-speed manual
transmission, which was the correct combination for buyers who
wanted maximum performance rather than convenience. The 1970 model
year was the final year Chevrolet marketed the engine displacement
as '396.' The actual displacement had been quietly bored to 402
cubic inches starting in 1970, but Chevrolet continued to badge
these cars as 396s for that model year because the 396 name carried
weight with buyers. The badging on this car accurately reflects how
it left the factory. Features List 396ci Turbo-Jet L78 375hp Big

under the cowl induction hood is the L78 variant, rated at 375
horsepower and 415 lb-ft of torque from the factory. This engine
used solid valve springs, an aggressive hydraulic camshaft, an 800
cfm Holley four-barrel carburetor, and 11.0:1 compression. It was
not a subtle engine. Chevrolet built it for buyers who wanted to
use it. The cowl induction hood feeds cooler, denser outside air
directly into the carburetor from the high-pressure area at the
base of the windshield, a system that provided a measurable intake
charge advantage over a standard hood setup. The 4-speed manual
transmission is the correct companion to the L78. When this
combination was new, Car and Driver and other publications
consistently tested similarly equipped Novas in the high 13-second
range in the quarter mile, with 60 mph arriving in under six
seconds �€" numbers that placed the Nova SS 396 ahead of many
better-known competitors. The undercarriage photographs show a
solid, clean structure with no visible rust or patch repair, which
matters considerably when evaluating a car of this age from any
part of the country, but especially so for cars with an unknown
history. Interior The black vinyl interior is correct and
well-suited to a car spec'd at this level. The center console runs
between the bucket seats and houses the shifter for the 4-speed,
keeping the mechanical relationship between driver and drivetrain
as direct as it should be. The dashboard tachometer is mounted in
the instrument cluster, giving the driver accurate engine speed
information without requiring an aftermarket pod on the column or
dash. The SS steering wheel �€" a specific option for the Super
Sport package �€" provides a smaller diameter
