The name on these valve covers has shown up on three completely different Chevrolet engines across five decades, and every single time it’s meant one thing: this is the Camaro that isn’t messing around. Today’s version makes 455 horsepower and spits flames on overrun, but the badge traces straight back to a drag-strip-born small-block from 1970. Read on to find out what actually connects a modern Camaro SS to a Z/28 from half a century earlier.
Long before this restomod’s ceramic headers and chrome mags, the 1932 Ford roadster had already become the battleground for hot rodding’s biggest debate: Ford body, Chevy heart. Once the small-block Chevy V8 proved itself in the mid-1950s, legendary builds swapped out their Ford flatheads, and this build carries that same tradition forward.
The 1984 Corvette was the car Chevrolet skipped an entire model year to get right, and it arrived with a chassis so stiff that magazines complained about it while recording the highest skidpad number they had ever measured on a production car. Its 205-horsepower Cross-Fire Injection V8 was the weak link in an otherwise radical package. It still outsold every other C4 model year. Read on for what made it matter.
Shot at the historic Raceway Park in Englishtown, New Jersey, this amateur upload from daredevil7442 captures a lineup of Hemi and big-block Mopar muscle running the quarter mile at one of the East Coast’s most storied drag strips. It’s grassroots drag racing rather than a professional NHRA broadcast, but the track underneath these cars has hosted some of the sport’s biggest names for decades. Watch to see American muscle running down a strip with genuine drag racing pedigree.
American muscle cars didn’t die from a single law. Insurance surcharges, emissions rules that cut a 450-horsepower Chevelle engine down to 200 horsepower, and the 1973 oil crisis all hit within a few years of each other. The 1980s comeback cars, like the 302 Mustang and third-gen Camaro, were built for survival, not revival. Read on for how the technology that actually solved the problem didn’t show up for another fifteen years, and why today’s 700-horsepower factory V8s owe more to those lean years than most enthusiasts realize.
Nearly two decades before airbags became mandatory, General Motors quietly built and sold them, first on government fleet cars, then as a factory option across four full-size luxury nameplates. Here is the surprisingly early and short-lived story of GM’s Air Cushion Restraint System, and why the technology vanished from showrooms for almost twenty years.
In 1965, Chevrolet sold more than one million Impalas in a single year — an all-time industry record that has never been broken. Over the next five years the car would get outshined by its own spinoff, borrow styling cues from the Corvette, and quietly absorb a wave of new federal safety mandates. Read on to find out how a record-setting best-seller ended up playing second fiddle to the model it created.
Chevrolet’s ‘W’ series big block ran into a hard power ceiling around 6,500 rpm, prompting a near-total redesign that became the Mark IV, nicknamed the ‘porcupine’ engine for its distinctive splayed valve angles. The new architecture kept key ‘W’ features like side-oiling and Moraine main bearings while dramatically improving high-rpm breathing. Read on to find out exactly what changed under the valve covers.
Pontiac built the first Firebird in barely six months after General Motors killed its pitch for a genuine two-seat sports car, borrowing GTO taillights and a shared Camaro platform to hit showrooms by February 1967. Four completely different engines, from a mild inline-six to a 400-cubic-inch V8 pulled from the GTO, all wore the same sheet metal, and only 697 of the ultra-rare 1969 Trans Am package were ever built. Read on to find out which engines actually made this car a legend.
Ford spent months teasing the next Shelby GT500 in camouflage and speculation before confirming it for the 2020 model year. Spy shots revealed a wider front track, massive Brembo brakes, and a supercharged version of the GT350’s 5.2-liter V8, while rumors pointed toward horsepower figures that dwarfed the outgoing GT500’s 662. Read on to find out how close the leaked details actually came to the car Ford eventually built.
New emissions rules were reshaping every engine bay in Detroit by 1975, and the Pontiac LeMans found itself right in the middle of that shift — still offering a genuine 400-cubic-inch V8 alongside its first catalytic converter. Here’s how Pontiac balanced compliance and horsepower in one of the most transitional model years of the era, plus a closer look at the car pictured here.
This 1947 Mercury started life as Ford’s answer to a price gap between its own lineup and Lincoln — a modestly powered flathead V8 coupe built for buyers who wanted more than a Ford without paying for a Lincoln. Decades later, this restomod swaps that original 100-horsepower flathead for a Corvette-sourced LT1, proving the body’s lines were worth preserving long after the original mission Mercury built it for had faded.
Modern muscle cars have quietly turned into something closer to supercars, chasing sub-four-second sprints and skidpad numbers that would have embarrassed exotics a generation ago. Three very different philosophies, a 650-horsepower supercharged Camaro ZL1 1LE, a 707-horsepower Challenger Hellcat, and a flat-plane-crank Shelby GT350R that revs to 8,250 rpm, all land shockingly close on the stopwatch. Here is how they actually stack up, and why the pricing runs backwards.
Buick is not the first name most people reach for when the conversation turns to the quickest muscle cars of 1970 — which is precisely the mistake the Stage 1 package existed to correct. A GM rule change that year finally let Buick drop a full 455 into a midsize car, and period testers recorded quarter-mile times that embarrassed far louder reputations. Convertibles were rarer still. Read on for the numbers behind the most underrated muscle car of 1970.
