This nitrous-fed Camaro ZL1, nicknamed the Freedom Rocket, had already survived a 300-horsepower shot under one tuner’s setup. Then a new shop got involved, and the comment section has since turned into a full investigation of a possible jetting chart mix-up. Watch to see exactly where — and how violently — the engine finally lets go.
George was not hunting for a classic when he spotted a Buick Skylark with a for-sale sign in Lisbon, Ohio, in the summer of 2014; he just stopped for a closer look. What he found was a GS455-powered GSX tribute car with its original numbers-matching 350 engine stored safely away, parked in a garage alongside a small private muscle car collection. Read on to find out about the one-of-a-kind GM production mistake that makes a factory GS455 Stage I Skylark one of the rarest muscle cars of 1970.
By 1972 the muscle car era was ending in slow motion, and Buick’s Gran Sport had already been demoted from a standalone model back to an option package on the Skylark. This survivor still wears its factory paint, original interior, factory vinyl top, and a numbers-matching 350 four-barrel. Here is what actually changed in 1972, why the horsepower ratings dropped so sharply, and why an unmolested GS from this exact year is so hard to find.
Chevrolet’s 283 cubic inch V8 arrived in 1957 and, in fuel-injected form, made 283 horsepower, one per cubic inch, a marketing number too clean to be an accident. That same engine dominated NASCAR ovals so completely it was banned. This Bel Air carries the four-barrel version and a Powerglide, the combination most buyers actually drove home. Here is what made 283 cubic inches a turning point for Chevrolet.
For years General Motors banned engines larger than 400 cubic inches from its mid-size cars. When that rule lifted for 1970, Chevrolet immediately dropped a 454 into the Chevelle SS, and it arrived in two very different forms. The LS6 got the headlines at 450 horsepower, but the LS5 outsold it and outlasted it. Here is what separated the two engines and why an original LS5 survivor matters.
Dave Saruk’s 1971 Dodge Challenger R/T wears factory Hemi Orange paint over a genuine 426 Hemi engine, and according to viewers, its history traces back to a barn in Switzerland before making its way home. Dave’s search for the car started with sibling rivalry, after his brother-in-law bought a Hemi Challenger first. Filmed at the Muscle Car and Corvette Nationals in Rosemont, Illinois, this is one more entry in Lou Costabile’s ongoing hunt for great car stories. Watch to hear the full story.
A Shelby GT500 owner claiming roughly 800 horsepower at the wheels decided to call out every Dodge Hellcat he could find for a street race — a bold move given that stock Hellcats already run low-to-mid 11s from the factory. The result did not go the way the callout promised, and the comment section made sure everyone knew it. Between jokes about losing to sedans and suggestions to call out a Prius next time, this one became less about the race and more about what happens when trash talk meets a stopwatch. Watch to see how it actually played out.
American Motors built the Ambassador as its flagship for eighteen model years, and 1966 was the year the gamble finally paid off, with sales climbing to roughly 71,000 from under 19,000 just two years earlier. The DPL hardtop sat at the very top of that range with reclining buckets and AMC’s largest V8. Here is why an unrestored survivor from a brand this overlooked is genuinely harder to find than a big-name muscle car.
A full-size 1967 Ford LTD XL was built to coddle its owner with a hushed ride and chrome trim — not to embarrass drag racers. This Lime Gold example, part of the noted Brothers Collection, hides Ford’s factory R-Code 427 rated at 425 horsepower behind a four-speed manual, a combination so rare that dealers barely stocked it and Ford’s own brochures barely mention it existed. It’s one of only a handful of full-size Fords built this way. Watch to see just how much muscle Ford hid inside its plushest cruiser.
Alf’s 1965 Chevy II Nova SS still wears its original California dealer plates, decades after Hovey-Dallas Chevrolet first sold it — only now it’s a familiar sight near Seaview Road outside Adelaide, Australia, following a 2008 import. The car runs its factory 283 V8 and PowerGlide transmission, kept close to stock except for dual Flowmaster mufflers and a fresh set of mags. Read on to see how a documented, three-owner Nova crossed an ocean and stayed true to its roots.
Plymouth built 108 Hemi ‘Cuda hardtops for 1971 and just eleven convertibles, which is why this specific corner of the Mopar market operates on a completely different scale from everything around it. The car in question has covered 2,010 miles since new and was custom-ordered with the desirable boxes already ticked. Whether that adds up to a seven-figure asking price depends less on rarity than on paperwork. Here is what actually drives the numbers.
A 1955 Chevrolet convertible custom called Payback takes the body that introduced the small-block V8 to the world and rebuilds it with modern intent. Only 41,292 Bel Air convertibles left the factory that year, and decades of hot rodding have thinned that number considerably. Read on to find out what made 1955 the most consequential year in Chevrolet history and what it takes to earn a name like Payback.
The 1968 GTO was a complete redesign built around a gamble: a body-colored, energy-absorbing Endura front bumper with no chrome at all, something no mass-production car had tried. It won Motor Trend Car of the Year and reset how intermediate coupes were styled. A handful survive today still wearing factory paint, and that is not an accident. Read on for what makes an unrestored survivor worth more than a restoration.
A 1969 L88 Corvette, one of only 116 built and deliberately underrated by Chevrolet at 430 horsepower, takes on a 1972 Oldsmobile 442 W-30 officially rated at just 300 horsepower. A commenter who says they worked at Olds Experimental during this era insists that number was never accurate, and that a genuine W-30 could beat Mopars, GTOs, and Corvettes regularly. The race backs up the claim. Watch the run and read the insider testimony in the comments before trusting either car’s factory rating.
The 1949 Hudson Super Six hid a genuinely clever piece of engineering under its conservative styling: a lowered unibody shell mounted over a reinforced ladder frame, dropping the cabin floor below the frame rails for a lower center of gravity than most full-size American cars offered. Hudson called it Step-Down construction, and it gave the Super Six handling that outclassed rivals from Buick and Chrysler. Nearly 100,000 were built in 1949 alone — one of the more underappreciated engineering stories in postwar Detroit.
