Camaro RS-SS-Z28 options 1967 to 1969 cont…

Chevrolet built three very different Camaros under one badge in the late 1960s, one dressed to be noticed, one built to go fast, and one so quietly race-bred that Chevy barely admitted it existed. The RS brought hideaway headlights and showroom flash, the SS brought big-block muscle, and the unadvertised Z28 brought a 302 small-block engineered specifically to win Trans-Am races. Read on to find out how rare that racing option really was, and why so few dealers even knew to offer it.

By the late 1960s, Chevrolet was quietly running two different playbooks inside the same Camaro showroom, one built for buyers who wanted to be noticed, and one that barely existed on paper at all. The loud version came with hideaway headlights and badges plastered across every panel. The quiet version was a factory race car disguised as an ordinary coupe, sold through dealers who often did not fully understand what they had on the lot. Only a few hundred people ever found it that first year, and everyone else drove home in something that merely looked fast. What separated the Camaro that paced the Indianapolis 500 from the one built specifically to win at Trans-Am road courses?

Three Ways to Dress Up a Nova Underneath

The 1967 Camaro shared its platform with the Chevy Nova, using a semi-unibody design where the sheet metal itself added structural strength rather than relying purely on a separate frame. On top of that shared foundation, Chevrolet offered the RS as one of three appearance packages, adding hideaway headlights, back-up lights relocated into the bumper, a revised taillight treatment, rocker panel trim, and RS badging throughout. It was purely cosmetic, no engine or suspension changes came with it, but it transformed the Camaro’s face enough that RS-optioned cars are still instantly recognizable to Camaro spotters decades later.

SS Meant Business Under the Hood

Where the RS was about looks, the SS package meant a real engine upgrade: buyers chose between a 350-cubic-inch (5.7L) V8 or stepped up to the 396-cubic-inch (6.5L) big-block in either L35 or L78 form. The package also brought decorative hood-mounted air inlets, special striping, and SS badges stamped onto the gas cap, front fenders, grille, and horn button, making sure nobody mistook the car for a base coupe. Because RS and SS could be ordered together, 1967 produced a rare combination car, and one specific RS/SS convertible, powered by the 396, earned the honor of pacing that year’s Indianapolis 500.

The Option Chevy Never Advertised

Hidden away from the brochure entirely was the 1967 Z28, an unadvertised trim that dealers could order but rarely promoted to walk-in customers. It paired a 302-cubic-inch small-block, built with a 3-inch crankshaft and 4-inch piston bore, with an aluminum intake manifold and a four-barrel 780-cfm Holley carburetor. Chevrolet officially rated it at just 290 hp at 5,300 rpm, a number that undersold what the high-revving small-block could actually do. In reality, the engine made closer to 360 hp with a single four-barrel at higher rpm, and reports of dual four-barrel setups pushed output toward 400 hp between 6,800 and 7,000 rpm.

Built to Legally Race, Not Just Look Fast

The 302’s odd displacement was not an accident, it was engineered specifically to qualify for the Trans-Am racing series, which required a production car available to the public, an engine under 305 cubic inches, and less than one horsepower per cubic inch of displacement, a rule aimed at keeping insurance costs manageable across the industry. The Z28 package added heavy-duty suspension, front disc brakes, and a close-ratio Muncie four-speed transmission, with Positraction offered as an option. Fender badging, racing stripes on the hood and trunk, and the ability to combine it with the RS package rounded out a car built to win races first and turn heads second.

How Rare the Z28 Really Was

Of the 221,306 Camaros Chevrolet sold in 1967, only 64,842 carried the RS option and 34,411 wore SS badging, a group that included 100 RS/SS pace car replicas built to commemorate the Indy honor. The Z28, by comparison, found just 602 buyers that first year, a fraction of a percent of total Camaro production, and proof of how deliberately Chevrolet kept the option under the radar while it built a racing reputation on the track instead of in showroom traffic.

1969 Widened the Engine Lineup Dramatically

By 1969, the RS/SS combination had grown into a genuine engine buffet, with five different powerplants spanning 350 to 396 cubic inches and factory horsepower ratings between 300 and 375. Dealers went even further off the official order sheet, authorized to install a 427-cubic-inch engine rated at 430 hp for customers willing to ask for it directly. Most of these engines paired with a standard three-speed manual, though both a three-speed automatic and a four-speed manual remained on the table for buyers who wanted to shift for themselves.

Cowl Induction Joins the Z28 Options List

The 1969 Z28 also introduced the cowl induction hood, a functional scoop that pulled cooler, denser air from the high-pressure zone at the base of the windshield rather than from the hot engine bay air earlier cars relied on. It was a small but meaningful refinement, part of a broader pattern of Chevrolet quietly improving the Z28’s actual performance year over year even as the car’s marketing stayed relatively muted compared to the RS and SS packages that got most of the showroom attention.

A Three-Tier System That Still Confuses Buyers Today

Because RS, SS, and Z28 could all be combined or ordered independently, first-generation Camaros from this era exist in dozens of factory configurations, which makes correctly identifying an original car far more complicated than checking a single badge. A car wearing RS trim might carry the mild 350, the big-block 396, or in rare cases the race-bred Z28 hardware underneath, and only the factory build sheet or trim tag tells the real story. That complexity is exactly why these Camaros remain such a deep rabbit hole for collectors and why documentation matters as much as the sheet metal itself.

Why the Z28 Legend Still Drives Values Today

Modern collector markets have caught up to what Trans-Am racers already knew in 1967, genuine, numbers-matching Z28s from this era command a steep premium over comparably equipped RS or SS cars, precisely because so few were built and even fewer survive with their original 302 small-block intact. That scarcity, combined with the model’s legitimate racing pedigree, means a verified 1967-1969 Z28 sits near the top of most first-generation Camaro want lists, right alongside the rare RS/SS Indy pace car replicas that started this whole three-package system in the first place.
