First-generation Chevrolet Camaro

The first-generation Chevrolet Camaro is an American pony car introduced by Chevrolet in the fall of 1966 for the 1967 model year. It used a brand-new rear-wheel-drive GM F-body platform and was available as a 2-door, 2+2 seat, hardtop, and convertible. The F-body was shared with the Pontiac Firebird for all generations. A 230 cu in Chevrolet straight-6 was standard, with several Chevy V8s available as options. The first-generation Camaro was built through the 1969 model year.

Almost all of 1967–1969 Camaros were built in the two U.S. assembly plants: Norwood, Ohio, and Van Nuys, California. There were also five non-U.S. Camaro assembly plants in countries that required local assembly and content. These plants were located in the Philippines, Belgium, Switzerland, Venezuela, and Peru.

Options

The debut Camaro's standard drivetrain was a Chevrolet Turbo-Thrift straight-6 engine rated at at 4400 rpm and of torque at 1600 rpm, coupled to a 3-speed manual transmission.

To keep up with other manufacturers in the ever more crowded pony car niche, a selection of optional base-model and high-performance V8s was offered, as well as a variety of optional manual and automatic transmissions.

Eight different engines were available in the 1967 Camaro, 10 in 1968, and 12 in 1969. Optional transmissions during the first-generation model run included the two-speed "Powerglide" automatic transmission, and a four-speed manual, available with any engine. A three-speed " Turbo Hydra-Matic 350" automatic became available on most V8s starting in 1968. The optional automatic for SS 396 cars was the three-speed Turbo 400. In 1969, a semi-automatic "Torque-Drive" two-speed transmission was available on six-cylinder models.

Packages

The Camaro was offered in three main optional packages:

* The RS appearance package. Available on any model, it included hidden headlights (with horizontally retractable doors that hid behind the grille when opened), revised taillights with back-up lights under the rear bumper, RS badging, and bright exterior trim.
* The SS performance package, consisting of a or V8s and chassis upgrades to handle the additional power and deliver better handling. The SS featured non-functional air inlets on the hood, special striping, and SS badging.
* The Z/28 performance package, designed to allow the Camaro to compete in the SCCA Trans-Am Series. It included a solid-lifter V8, 4-speed transmission, power front disc brakes, 12-bolt rear axle, 15" wheels, heavy duty suspension and a pair of wide "skunk" stripes down the hood and trunk lid. The Z/28 offered vibrant street-legal performance, but required numerous additional modifications to be raced competitively.

1967

The 1967 styling was done by the same team that had designed the 1965 second-generation Corvair. The Camaro shared the subframe / semi-unibody design with the 1968 Chevy II Nova. Almost 80 factory-and 40 dealer-installed options were offered, including the RS, SS, and Z/28 main trim packages.

SS

The SS included a producing at 4800 rpm and at 3200 rpm of torque; and the ''L35'' and ''L78'' big-block V8 engines producing or at 5600 rpm and at 3600 rpm of torque were available. The SS featured non-functional air inlets on the hood, special striping, and SS badging on the grille, front fenders, gas cap, and horn button. In 1967, a Camaro RS/SS convertible with a 396 engine paced the Indianapolis 500; 100 replicas were sold to the public.

Z/28

The Z/28 option code was introduced in December 1966 for the 1967 model year. It was the brainchild of Vince Piggins, who conceived offering "virtually race-ready" Camaros for sale from any Chevrolet dealer. This option package was not mentioned in any sales literature, so it was unknown to most buyers.

The Z/28 featured a high-output small-block V8 that had been designed for competing in the 5 litre (305 cu in) class of the then-popular Trans-Am racing series. It had a strongly over-square, high-revving bore and stroke, with an aluminum intake manifold, and a 4-barrel vacuum secondary high-volume 780 cfm Holley carburetor. It took Ford until 1969 to mount a head-to-head competitor: the Boss 302 Mustang.

Advertised power of the 302 V8 was at 5300 rpm — intentionally under-rated (a common practice at the time) so Chevrolet could keep claimed horsepower under 1 per cubic inch for insurance premium calculations and racing classification.

The Z/28 also came with upgraded suspension, power front disc brakes, a 4-speed Muncie close-ratio manual transmission and a 12-bolt rear axle. Posi-traction was optional. Wide racing stripes on the hood and trunk lid could be deleted at no charge, '302' front fender emblems came on the 1967 and early 1968 cars, 'Z/28' emblems in the late 1968s and 1969s.

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. An optional cowl induction hood became available in 1969. 15-inch rally wheels were included with Z/28s, while all other 1967-9 Camaros had 14-inch wheels.

The origin of the Z/28 nameplate came from the RPO codes – RPO Z28 was the code for the Special Performance Package. RPO Z27 was for the Super Sport package. A total of 602 Z/28s equipped Camaros were sold in 1967.

The Z/28 option would return in 1968, continue into the second generation in 1970, drop the / from its name in 1972, and remain available as the Z28 through 1987. It would return for 1991 and continue to the end of the fourth generation in 2002. It would then reappear in 2014 in the fifth generation rebadged back to the Z/28 (though 2015). There was no sixth generation Z/28.

Swiss-assembled cars

Cars assembled in Switzerland, at GM's local facility in Biel, were all coupes with a Chevrolet V8 that produced at 4800 rpm and at 2400 rpm. This engine was not available in contemporary Camaros built in the United States. The Swiss-built Camaros were unavailable with the three-speed manual and had a limited-slip differential and front disc brakes as standard. Some additional safety equipment was also standard.

1968

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 as part of safety requirements 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 producing at 5200 rpm and of torque at 3400 rpm big block engine was added as an option for the SS, and the Z/28 appeared in Camaro brochures, and nearly 7,200 were sold. The was not available as a Regular Production Option (RPO).

Chevrolet's Special Production Division 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 built. The car was parked in the executive garage which Pete Estes had access to. Upon driving the vehicle, he promptly approved promoting the Z/28. A 1968 Z/28 competed in the 1971 British Saloon Car Championship at Crystal Palace in a three-way battle for the lead, a race which was later featured in the "Sporting Moments" episode of BBC's '' 100 Greatest'' series.

1969

The 1969 Camaro carried over the previous year's drivetrain and major mechanical components, but all-new sheet metal, except the hood, trunk lid, and roof, gave the car a new look. The grille was redesigned with sharper V and deeply inset headlights. New door skins, rear quarter panels, and rear valance panel made the car look lower and wider. This styling would only serve for the 1969 model year.

To increase competitiveness in the SCCA Trans-Am racing series, optional four-wheel disc brakes with four-piston calipers were made available during the year, under RPO JL8, for US$500.30.General Motors documentation This system used components from the Corvette and made for a significant improvement in the braking capability and was a key to winning the Trans-Am championship. The option was expensive and only 206 units were produced.

The Rally Sport (RS) option, RPO Z22, included a unique black-painted grille with concealed headlights and headlight washers, fender striping (except when sport striping or Z/28 Special Performance Package is specified), simulated rear fender louvers, front and rear wheel opening moldings, black body sill, RS emblems on grille, steering wheel and rear panel, Rally Sport front fender nameplates, bright accented taillights, back-up lights below rear bumper; hardtops got bright roof drip moldings. The RS option cost $131.65, with 37,773 orders filled.

Z/28 sales soared from 7,200 to over 20,000, available with the same small block producing at 5800 rpm and of torque at 4200 rpm. It was backed by Muncie manual four-speed transission with a new-for-69 standard Hurst shifter and connected to a 12-bolt rear axle with standard 3.73 gears. The 302 featured 11:1 compression, forged pistons, forged steel crankshaft and connecting rods, solid lifters, and Holley carburetor on a dual-plane intake manifold. A dual four-barrel crossram intake manifold was available as a dealer-installed option.

The 1969 model year was extended into November 1969, due to manufacturing problems that delayed the introduction of the second generation model planned for 1970.

COPO 427s

A GM corporate edict forbade its Divisions from installing engines larger than in mid-size and smaller models. Requests from dealers (notably Don Yenko in PA, Baldwin-Motion in NY, Nickey in IL and Dana in CA) who had been dealer-installing engines in the Camaro prompted Chevrolet to use an ordering process usually used on fleet and special orders (taxis, trucks, etc.) to offer 427 engines in the Camaro. Two Central Office Production Orders (COPO), numbers 9560 and 9561, were offered in the 1969 model year.

The COPO 9561 used the cast iron block/cast iron heads, solid-lifter L72 big-block engine, rated at SAE gross at 5600 rpm and of torque at 4000 rpm. Yenko ordered 201 of these cars to convert them into Yenko Camaros. Other dealers also became aware of the L72 engine package. Around 1,000 Camaros were fitted with the L72 engine option.

The COPO 9560 used an all-aluminum ZL1 designed specifically for drag racing, where weight savings were at an absolute premium. The package was conceived by drag racer Dick Harrell, and ordered through Fred Gibb Chevrolet in La Harpe, IL, to enter NHRA Super Stock racing. A total of 69 ZL1 Camaros were produced. The engine alone cost over US$4,000—or more than an entire base V8 Camaro. Rated at gross at 5200 rpm and of torque at 4400 rpm/ SAE net "as installed", it could produce over 500 gross with exhaust changes and tuning.

The ZL1 engines were manufactured at the Tonawanda Assembly Plant before being installed in Corvettes and Camaros or sold over the counter to racers. Each took 16 hours to be hand-assembled in a room that Corvette Chief Engineer Zora Arkus-Duntov described as "surgically clean."
