Muscle Cars - Chevy Nova SS

chevy nova ss grillesAn extensive restyle came in 1968, when the station wagon and Sport Coupe were discontinued. This body style continued (with minor revisions) through 1974. One notable change was the front subframe assembly - as compared with Ford, Chrysler and AMC, in whose cars the entire front suspension was integrated with the bodyshell, a separate subframe housing the powertrain and front suspension (similar to the front part of the frame of GM's full-size, full-framed vehicles) replaced the earlier style. The front subframe design was unique for the Nova, the Camaro introduced a year earlier was the first to incorporate such a design; the redesigned Nova was pushed a year back to 1968 instead of 1967.

The 153 cu in (2.51 L) four-cylinder engine was offered between 1968 and 1970, then was dropped due to lack of interest (besides its other usage in the Jeep DJ-5A a.k.a. the Postal Jeep). Far more popular were the 250 cu in (4.1 L) six-cylinder and the base 307 cu in (5.03 L) V8, which replaced the 283 cu in (4.64 L) V8 offered in previous years. At mid-year, a semi-automatic transmission based on the Powerglide called the Torque-Drive was introduced as a low-cost option for shiftless motoring for both the four and six-cylinder engines. The two-speed Powerglide was still the only fully-automatic transmission available with most engines.

Front disc brakes were optional on the 1968 Nova SS. Optional engines included two versions of the big-block 396 cu in (6.5 l) V8 rated at 350 hp (260 kW) and 375 hp (280kW), which went for US$348. Both engines were offered with a choice of transmissions including the M-21 close-ratio four-speed manual, the heavy-duty M-22 "Rock Crusher" four-speed manual, or the three-speed Turbo-Hydramatic 400 automatic transmission.

Basically a carryover from 1969; the side markers and taillight lenses for the 1970 Nova were wider and positioned slightly differently. This was the final year for the SS396. All other engines were carried over including the seldom-ordered four-cylinder which was in its final year. The car finally became simply the Chevrolet Nova this year after two years of transitional nameplates (Chevy II Nova in 1968 and Chevrolet Chevy Nova in 1969). Approximately 177 Central Office Production Order (COPO) Novas were ordered, with 175 converted by Yenko Chevrolet. The other two were sold in Canada. The Nova was used in Trans-Am racing this year.

The Rally kit included black or white stripes that ran the length of the car and around the back, a Rally Nova sticker on the driver's side of the hood, Rally wheels, multi-leaf rear springs, and a "sport" body colored drivers side mirror that was adjustable from the interior. A luxury-themed Nova Custom, later called the Nova LN, became part of the model lineup which included upgraded upholstery, floor mats and more exterior trim.

The SS option was still available but became more of a sporty trim package than a performance offering and now offered with any Nova engine, much like the 1963 to 1967 Nova SS. An interesting model was the 'Spirit of America' Nova introduced in 1974. In anticipation of the US bicentennial in 1976, these vehicles were painted white and featured blue and red accent stripes as well as red and blue interior carpets and fabrics. Oldsmobile and Buick entered the compact car market; both the Apollo and Omega debuted, using the same bodystyles from the Nova lineup. Additional options were included on these Nova-like models, such as lighting under the dashboard and in the glove compartment.
