The first-generation Chevrolet Camaro appeared on September 26, 1966, for the 1967 model year on an all brand new rear-wheel drive GM F-body platform and would be available as a 2-door, 2+2 seat, coupe or convertible with a choice of six-cylinder and V8 powerplants. The first-gen Camaro would last up through the 1969 model year.
1968 saw the deletion of the side vent windows and the introduction of Astro Ventilation, a fresh-air-inlet system. Also added were side marker lights on the front fenders which was a government requirement for all 68 vehicles, a more pointed front grille, a front spoiler, and divided rear taillights. The front running lights (on non-RS models) were also changed from circular to oval. The big block SS models received chrome hood inserts that imitated velocity stacks. The shock absorber mounting was staggered to resolve wheel hop issues and higher performance models received multi-leaf rear springs instead of single-leaf units. A 396 cu in (6.5 L) 350 hp (261 kW) big block engine was added as an option for the SS, and the Z28 appeared in Camaro brochures. The 427 cu in (7.0 l) was not available as a Regular Production Option (RPO). Several specialty after-market dealers, such as Baldwin-Motion Performance Combine, Long Island, NY, offered the 427 as a replacement for the factory-supplied 396 cid engine. 7,199 Z28s were sold in 1968.
