The styling of the 1968 Camaro was very similar to the 1967 design. With the introduction of Astro Ventilation, a fresh-air-inlet system, the side vent windows were deleted. Side marker lights were added on the front and rear fenders which was a government requirement for all 1968 vehicles. It also had a more pointed front grille 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 and low-gloss black rear tail light panel.
The rear 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) producing 350 hp (261 kW) at 5200 rpm and 415 lb⋅ft (563 N⋅m) of torque at 3400 rpm big block engine was added as an option for the SS,[16] and the Z28 appeared in Camaro brochures. The 427 cu in (7.0 L) was not available as a Regular Production Option (RPO). Several dealers, such as Baldwin-Motion, Dana, and Yenko, offered the 427 as a dealer-installed replacement for the factory-supplied 396 cu in (6.5 L) engine.
Chevrolet's Special Production Division wanted to promote the Z28. They had to convince Chevrolet's General Manager Pete Estes, but the General Manager only drove convertible vehicles, and the Z/28 was never produced as a convertible. A Central Office Production Order (COPO) was placed for the only Z/28 convertible Camaro ever created.[17] The car was placed in the executive garage which Pete Estes had access to. Upon driving the vehicle, he promptly gave approval for promotion of the Z/28. A 1968 Z/28 famously competed in the 1971 British Saloon Car Championship at Crystal Palace[18] in a three-way battle for the lead, a race which was later featured in the BBC's “100 Greatest Sporting Moments”.
