1978 CHEVROLET CORVETTE CHANGES
The biggest change to the ’78 model was the new back window. Gone was flat window in the flying buttress roof, in its place was an elegantly shaped and very aerodynamic fastback rear window. It was fixed, it didn’t open, but it greatly expanded the luggage capacity of the car. Rear visibility was also greatly improved. There was a new instrument cluster that matched the aircraft style of the new center console, and new door panels. A glove box appeared on the passenger side, replacing the old map pocket. New options included power locks, a power antenna, dual rear speakers and a factory CB radio. The gas tank capacity was increased from 17 to 24 gallons on all cars, and a space saver spare tire was adopted to make room for it. Tire sizes switched over to metric in ’78 with P225/70R15 as the standard size with P255/60R15s optional with some factory fender trimming.
1978 CHEVROLET CORVETTE ENGINE OPTIONS,BR> The base engine was now the L-48 350ci (5.7L) small block V8, rated at 185hp in 49 states, and 175hp in California, due to its stricter smog regs. Outside the Golden State an L-48-equipped ’78 Vette took 7.8 seconds zero-to-60 with a top speed of 123mph. The chromed steel distributor cover was eliminated in favor of a black plastic unit. The single snorkel air cleaner was replaced by a dual snorkel unit on the L-82 350 V8, rated at 220hp, which was good for 6.6 seconds to 60 and a 127mph top speed. The L-82 also got an aluminum intake manifold that saved 24 pounds of weight compared to the old cast iron manifold.
