The C3 generation of Corvettes saw the light of day for 1968, with the now fashionable 'coke bottle' waistline. Underneath the chassis of the C2 was retained, as was the 327cu in (5359cc) V8. The new body was better aerodynamically even though it was less roomy inside. Larry Shinoda had designed the Mako II concept car in 1964 and this was worked up by David Holls, Zora Arkus-Duntov and Henry Haga. The coupe was given a removable targa roof, but a convertible model was also offered. Engine choices included the 327cu in V8 as well as the 7litre 427cu in that had first appeared in 1966. 1968 Corvettes did not carry the 'Stingray' name, but in 1969 'Stingray' badges were affixed (until 1976) and criticisms about the 1968 Corvette were addressed. For 1970 new front 'ice cube' grilles were given to the car, and a square-patterned wing vent took the place of the simple three louvres. A new 454cu in (7,440cc) V8 was available at the top of the range, and there were new 350cu in motors further down the model range. The 1973 C3 Corvette was given a deformable nose and tail, losing its 'ice cube' grille, and having the side vent much simplified. Although both the base model 350cu in V8 and the monster 454cu in motor were still available, emmissions regulations had severely strangled their outputs. The C3 continued to evolve, gaining a new fastback rear window for 1978, a new 'shovel' nose for 1980, and 1982 was the final year before the C4 Corvette replaced it.
