The Z/28 option code featured a 302 small-block V-8 engine, with a round flange on the crankshaft, aluminum intake manifold, and standard 780CFM 4-barrel Holly carburetor with vacuum secondary. The V-8 engine was designed to race in the Trans Am series.
Advertised power of the z/28 302 engine was listed at 290hp. This was an under-rated figure because this 302 small-block V-8 engine could provide 1 horsepower/cubic inch, mostly due to the straight-through and unobstructed design of the ports in the heads and aluminum intake manifold.
The Chevy Camaro Z/28 included upgraded suspension, ‘Z/28' emblems for the fenders, and racing stripes on the hood . In 1969 it was possible to combine the Z/28 package with the RS package.
Only 602 Camaro Z/28s were sold in 1967. The 1967 and 1968 Z/28s did not have raised cowl induction hoods as did the 1969 Z/28s. The 1967 Z/28 received air from an open element air cleaner or from an optional cowl plenum duct attached to the side of the air cleaner that ran to the firewall and got air from the cowl vents. 15-inch rally wheels, were included with 1967 Z/28s had while all other 1967 Camaros had 14-inch wheels.
