Chevrolet Camaro 1970 Pro Touring

This 1970 Camaro’s split front bumper is one of the most misunderstood details in the entire pony car world, and this candy-painted, big-block example backs the look up with a full custom interior from Steve Holcomb’s shop. Read on to find out where the split bumper actually came from, and why it can’t tell you what’s really under the hood.

The split bumper look on a 1970 Camaro is one of those details that separates the enthusiasts from the casual fans, and there’s actually a fair bit of genuine confusion out there about what it means and where it originally came from. Some assume any split-bumper car must automatically be a genuine RS, others assume it automatically means SS instead, and plenty of restorers have been fooled entirely over the years because of how easy this particular look is to fake convincingly with modern reproduction parts. This particular Camaro leans hard into that split-bumper styling and backs it up with a genuine big block and a custom interior that leaves no doubt whatsoever about its actual intentions. So where did that split bumper actually come from in the first place, and does it really tell you anything meaningful about what’s under the hood? The answer surprises even longtime Camaro owners.

The Truth About the Split Bumper Look

Those independent front bumperettes were originally part of the RS package, officially known internally at Chevrolet as RPO Z22, which was purely a styling and appearance option featuring a distinctive black-painted grille insert, a molded urethane nose panel, and parking lights mounted directly onto the grille itself rather than tucked into the bumper the way most other Camaros had them. It had absolutely nothing whatsoever to do with what engine happened to sit behind that grille on any individual car that came down the line.

Why the RS Badge Doesn’t Mean Performance

Here’s the part that trips people up most often when they’re shopping for one of these cars today: the RS package had zero connection to any engine or suspension upgrades of any kind, meaning a split-bumper car could just as easily be a base six-cylinder daily cruiser as a genuine big-block monster underneath that sharp-looking front end. Chevrolet marketed the RS purely as a styling statement aimed at buyers who wanted their Camaro to look sportier in the driveway without necessarily paying for the mechanical upgrades that came bundled into other option packages that same model year. The badge only ever promised a specific visual look on the outside, never a specific level of performance or engine displacement hiding underneath it.

Where the Real Muscle Actually Came From

The real performance instead came from RPO Z27, the genuine SS package, which brought along a 300-horsepower 350 small block — or the optional 396 cubic-inch big block for buyers who wanted even more — along with power front disc brakes, dual exhaust, and other supporting hardware, and critically, it could be ordered completely independent of the RS trim on the very same order form. A single Camaro could leave the factory as RS alone, SS alone, both options together, or neither one at all, in almost any combination Chevrolet’s order sheet technically allowed that entire model year. Chevrolet even offered a combined RS/SS option code for buyers who wanted both packages together from the factory, which is part of why so many surviving cars today wear the split bumper alongside genuine big-block credentials rather than one or the other alone.

Why So Many Owners Added the Look Later

Because the split-bumper appearance proved so enduringly popular with buyers who never got it originally from the factory, plenty of owners who didn’t order the RS package back in 1970 went back years later and retrofitted the look onto their non-RS Camaros using widely available reproduction parts. That’s exactly why the split bumper alone genuinely can’t tell you anything definitive about a car’s true factory build sheet today, decades removed from the original assembly line in Norwood or Van Nuys. Reproduction RS grille kits have been available through the classic parts aftermarket for decades now, priced affordably enough that adding the look to a non-RS Camaro has never required much more than an afternoon in the garage and a modest parts-house budget.

Verifying a Real RS Today

Verifying a genuine RS today comes down entirely to the cowl tag and trim tag codes stamped directly onto the car at the factory when it was originally built, not the bumper treatment sitting on the car decades later after who knows how many previous owners and repaints along the way. Those coded metal tags remain the only truly reliable paper trail linking any given Camaro back to its actual original factory configuration and options.

Backing Up the Look With Real Muscle

Whatever this particular car started out as underneath its current sheet metal, it’s certainly not leaving anything to the imagination now. A genuine big block rumbling under the hood, candy paint that pops off every single angle in direct sunlight, and a full custom interior handled personally by Steve Holcomb’s shop mean this Camaro earns its aggressive stance rather than just wearing it for show the way so many purely cosmetic retrofit cars unfortunately do.

A Custom Interior That Matches the Ambition

Holcomb’s Pro Auto Custom Interiors has built a genuinely solid reputation within the pro-touring community over the years for exactly this kind of detailed, meticulous work — upholstery and trim executed to a standard that matches, rather than undercuts, the considerable effort already put into the drivetrain and bodywork surrounding it on a serious build like this.

Split Bumper Camaros in Today’s Market

That lingering retrofit confusion hasn’t slowed demand for the split-bumper look one single bit among buyers and builders alike across the hobby. Split-bumper second-generation Camaros remain some of the most requested restoration and build targets on the market today, regardless of whether the underlying donor car actually started life as a genuine factory RS or not.

Reading a Camaro’s Cowl Tag

A second-gen Camaro’s cowl tag sits on the firewall just below the windshield, stamped with a coded string that spells out the build date, assembly plant, trim level, and paint codes all at once, and learning to read it is the first real skill any serious second-gen buyer picks up. It won’t tell you whether a car wearing the split-bumper look today was born that way at the factory, but paired with the broadcast sheet, it’s the closest thing to a genuine factory paper trail this generation of Camaro has ever had.
