Camaro2 Z28
The Chevrolet Camaro Z/28 second generation, produced from 1970 to 1981, represents performance variant of redesigned Camaro featuring longer, lower, wider dimensions than first generation with convertible body style eliminated. Initial 1970 Z/28 featured LT1 350 cubic inch (5.7-liter) V8 producing 360 horsepower at 6,000 rpm and 380 lb-ft torque at 4,000 rpm with solid lifters, 11:1 compression ratio, and 6,500 rpm redline. Heavy-duty suspension, Positraction limited-slip differential, and performance-focused package priced at 72.95 attracted 8,733 buyers. Power declined drastically through mid-1970s due to emissions regulations with 350 V8 producing just 245 horsepower in 1973 Z28, and option dropped entirely for 1975-1976 models.
Z28 revival occurred in spring 1977 as dedicated model (1977½) powered by 350 cubic inch LM1 V8 with four-barrel carburetor producing 185 horsepower, reduced to 175 horsepower with California emissions equipment. Final years 1980-1981 saw output increase to 190 horsepower though 1981 350 engine only available with automatic transmission. The second-generation Z/28 represents challenging era in American performance car development navigating emissions regulations and fuel economy standards while maintaining muscle car heritage. The combination of evolution from powerful 360-horsepower LT1 beginning to emissions-constrained latter years, distinctive second-generation styling with aggressive proportions, Z/28 performance package maintaining sporting character throughout production, and historical significance representing muscle car transition through regulatory challenges makes second-generation Z/28 important American performance car documenting industry adaptation to changing requirements.
