Chevrolet Camaro 1973 – 350 5.7L V8

This clip’s exhaust note comes from a Z28-spec 350 that Chevrolet actually detuned by 10 horsepower that model year — a quiet signal of the performance slide about to hit the whole muscle car era. It also happens to be the last year this generation of Camaro wore its clean chrome-bumper styling.

Amazing exhaust sound!!

That exhaust note everyone comments on didn’t come from the base engine — it came from a specific, numbers-matching 350 that Chevrolet quietly detuned that very same year, even as it kept the internals strong enough to build real horsepower with the right tuning. This particular model year also marked the last time this generation of Camaro would wear its clean, chrome-bumper styling before federal regulations changed the car’s face for good, which makes the sound in this clip a kind of farewell nobody realized they were hearing at the time.

One Engine Code, Two Very Different Outputs

The standard 350 cubic-inch V8 offered this year made a modest 165 horsepower for daily-driver buyers, but checking the right option box unlocked a Z28-spec 350 rated at 245 horsepower and 280 lb-ft of torque — built with four-bolt main bearing caps, a forged steel crank, and big-valve cylinder heads that gave it real headroom over the base engine despite sharing the same displacement.

A Quiet Step Back From the Year Before

That 245-horsepower Z28 rating was actually down 10 horsepower from the previous model year, part of a broader industry-wide detuning trend as automakers adjusted compression ratios and tuning for tightening emissions rules. It’s a small number on paper, but it marks the exact point where Camaro performance began sliding rather than climbing, a trend that would accelerate hard the following year.

The Last Clean-Faced Camaro of Its Generation

This was also the final year this generation of Camaro would carry its original chrome-bumper styling — the next model year brought federally mandated reinforced bumpers that changed the car’s look for the rest of the generation’s run. Chevy dropped the Super Sport trim entirely this year and introduced the more upscale Type LT to replace it, signaling a broader shift away from outright performance branding and toward comfort-oriented trims, even as roughly 89,988 total Camaros still found buyers.

Why That Exhaust Note Still Turns Heads

Even with the power dip, a well-tuned Z28 350 from this year still delivers the deep, aggressive exhaust note that made this generation of Camaro a fan favorite in the first place — proof that horsepower numbers on a spec sheet don’t always tell the whole story of how a car actually sounds and feels on the road.
