Before the Pontiac GTO existed, corporate policy at General Motors made it impossible: no mid-size car could carry an engine over 330 cubic inches, period. John DeLorean and a small team of engineers built one anyway, testing it in nighttime street races before their bosses even knew it existed. This archival documentary traces how that quiet act of rule-breaking, plus a name borrowed from Ferrari, turned into the car that saved Pontiac and launched an entire era of American muscle. Watch to find out how close it came to never happening at all.

Buick only built 2,487 LeSabre convertibles for 1970, and this numbers-matching example carries the rare high-compression 350 that most buyers skipped over. Kept in the same Texas family since new, with original paperwork to prove it, it’s a documented survivor from the last year of a body style before Buick’s convertibles started disappearing for good. Here’s what made the high-compression option worth chasing.

A 1968 Plymouth GTX in B5 Blue with the rare 440+6 Six Pack setup would be notable on its own, but owner Kevin Plummer’s reason for buying it is what turns heads. He spent years chasing down the exact car his father owned when he was a boy, and he’s owned it since 2015. The comment section fills with strangers telling nearly identical stories about their own fathers.

The third-gen Chevrolet El Camino, 1968-1972, truly revved up the muscle car game with its Malibu-inspired style and Chevelle platform. In ’68, it flaunted options like posi-traction and a power disk brake for those who wanted to stop as impressively as they could go. The high-performance SS debuted, with engines roaring up to 375 bhp. By 1970, it could house a monstrous LS6 454 engine, racing through the quarter-mile in 13 seconds! Alas, emissions rules in ’71 took a bit of the vroom out of its zoom.

The Dodge Charger burst onto the scene in 1966, a sleek, fastback beauty that made its Coronet cousin look like the introverted sibling at a car family reunion. Luxuriously priced at $3,100, it was like a Marlin with a snazzier hat. Boasting hidden headlights and a taillight grin, it packed options from a 318-cubic-inch engine to the roaring 426 Hemi. In 1967, the Charger donned fender signals and a vinyl roof, but sales took a nosedive—guess not everyone wanted a car that could double as a disco.

No-prep racing strips away the safety net of a perfectly prepped track and dares drivers to make it work anyway, and this chopped-top Chevy Nova wagon is built for exactly that kind of chaos. A 632 cubic inch big block and two kits of nitrous turn a family hauler into something that launches like a bomb going off. Swamp Thing and crew brought it to Wichita’s No Prep Mayhem to prove it. Traction was optional; horsepower was not.

Officially, Ford didn’t build a 429-powered Mach 1 for 1972 — the big-block was gone after 1971, replaced by the 351 Cleveland. So how does this Screaming Yellow ’72 end up running one? The real story behind the swap is more interesting than the spec sheet.

Step into the jet age with Cadillac’s Series 62 from 1954 to 1956, where luxury meets aerodynamic audacity! The ’54 model dropped a few pounds—vertically—and flaunted a wraparound Eldorado windshield, making heads turn faster than its 17.5-second 0-60 mph. In ’55, Cadillac added tubeless tires and a “hockey stick” chrome trim, boosting sales to a record 118,190. By ’56, the Series 62 had a grill fancier than a Michelin-starred meal and could sprint to 60 mph in a brisk, for its size, 12 seconds.

Every 1970 SS 396 Chevelle is quietly lying to you — the badge says 396, but Chevrolet actually bored the engine out to 402 cubic inches that year. Here’s why the numbers stopped matching, and why it didn’t change a thing about how these cars perform.

Muscle cars aren’t just vehicles; they’re an attitude on wheels. Take Eleanor, the iconic 1967 Mustang from “Gone in 60 Seconds,” a true embodiment of muscle car spirit. These beasts, often powered by roaring V8 engines, dominated drag racing from the ’60s to ’80s. With insane torque and horsepower, they offer rides that’ll make your jaw drop—and maybe your toupee fly off. Thanks to innovations like Dodge’s all-wheel drive Challenger GT, driving these monsters isn’t just for sunny days anymore!

This twin-turbo Coyote Mustang rolled onto the dyno at Dynoedge running a modified Hellion turbo kit, reworked specifically to shorten intercooler piping and cut turbo lag, and posted a run that pushed toward nearly 1,400 horsepower at 26 psi of boost. Commenters zeroed in on the exhaust note as much as the numbers, calling it one of the best-sounding Coyotes they’d heard on a dyno. Watch the full pull to see exactly what a shortened-piping Hellion setup can do to a factory 5.0.

1961 was Ford’s first real shot at big-inch performance — a brand-new 390 V8 that could be optioned up past 400 horsepower a full year before the muscle car era officially began. This Sunliner keeps it old-school with no power assist anywhere. Here’s what made the early 390 Galaxies genuine sleepers.

Only two buyers in 1966 ordered a Ford 7-Litre convertible with the dual-carburetor R-Code 427 instead of the standard 428 — and this Brothers Collection car is one of them. Muscle Car Of The Week digs into what actually separates the R-Code’s cross-bolted big block from the ordinary version riding under most 7-Litre badges. Watch to see why this one stopped the crew in their tracks.

Superchargers and turbochargers both force more air into an engine, but they get there in fundamentally different ways — one mechanically driven off the crank, the other spinning on exhaust gas that would otherwise go to waste. That difference shapes everything from throttle response to how much horsepower a build can realistically chase. Watch the breakdown of exactly where each one wins.

Hertz rented race cars in 1966 — literally. Shelby built roughly 1,000 GT350H Mustangs for the ‘Rent-A-Racer’ program, and the black-and-gold color combo everyone remembers almost didn’t happen. Here’s the real story behind Shelby’s strangest, most famous customer.
