1970 marked the final year of high-compression muscle before emissions regulations and an unleaded fuel mandate changed everything — and this breakdown argues the real winner of that last great year came from an unexpected place. The Buick GS 455 Stage 1 quietly out-torqued nearly every rival on the market, backed up by a factory performance package most people never associated with Buick. One recent owner’s comment about a first ride with his daughter says it all.
Henry Ford quietly built at least eight boats in the early 1920s, and the last survivor, named Evangeline, carried a 450-horsepower V12 engine repurposed from a World War I fighter plane. It reportedly hit 49 mph in 1924, fast enough to outrun dedicated race boats of the day, before a fire at the Gold Cup ended Ford’s interest in racing on water for good.
Mike Musto gets behind the wheel of a genuinely rare 1969 Plymouth GTX for BIG MUSCLE, a car that wears its chips and scratches instead of hiding them under fresh paint. It is the kind of survivor that pulls personal stories out of the comment section, including one from a viewer whose brother came home from Vietnam to a car just like it. The GTX was Plymouth’s upscale answer to the muscle car boom, and this one still carries every mile of its history. Watch to see what Musto finds under the hood.
Erika Perrye had only owned her 1970 Buick GSX for a few months when Lou Costabile caught up with her and husband Bob in Lake Zurich, Illinois — but she already had strong opinions on why Buick’s most overlooked muscle car beats the obvious choices. Finished in bold Saturn Yellow with the torque-heavy 455 V8, this GSX is one of the rarest performance cars Buick ever built. Find out how a rare yellow Buick turned her into a genuine muscle car fan.
A car that quietly pulls to one side or wears through a set of tires years too early usually isn’t a tire problem at all — it’s an alignment problem hiding behind three angles most drivers have never heard of. CNET’s Brian Cooley breaks down camber, caster, and toe in plain language, and more than one viewer went out to check their own wheels after watching. Watch to find out which of the three you’re most likely feeling every time you drive.
Steve Dulcich and David Freiburger sit down to plan a small-block rebuild for a 1970 Dodge Challenger after its factory 318 got wrecked in a prior Roadkill Garage episode, and the conversation turns into a full history lesson on Chrysler’s LA-series V8. Viewers in the comments call it some of the best pure engine-nerd talk on the channel, right down to warnings about mixing cast and forged cranks. It is dense, it is technical, and Mopar fans cannot get enough of it. Watch to see what they land on for the rebuild.
The Fast Lane Car lines up a 707-horsepower Dodge Challenger Hellcat against a 306-horsepower Honda Civic Type R for a drag race, then does something more interesting: takes both cars onto a road course. The quarter-mile goes about how the horsepower gap suggests, but the track segment stirred up a comment section debate over which car actually won, complete with accusations that traction control skewed the result. Nearly 1.5 million viewers have weighed in since. Watch to see where the numbers stop telling the whole story.
Long before YouTube reviewers existed, TV host Bud Lindemann was putting cars through genuinely aggressive road tests — and this 1971 AMC Javelin SST got one of his more pointed reviews, directly comparing its styling to the Corvette before insisting “the Javelin is a handler.” Between AMC’s shared-block engine strategy and its little-known Group 19 racing parts program, this vintage clip explains why AMC loyalists remain some of the most devoted voices in muscle car culture. Watch the full vintage test.
Hagerty puts the classic carburetor-versus-EFI debate to an actual test, converting Parts Finder specialist Davin Reckow’s own 396 big-block Chevelle to a Holley Terminator throttle-body system and measuring the results every way that matters: feel, chassis dyno, eighth-mile drag strip times, and real-world gas mileage. It’s less opinion and more hard data for any big-block owner weighing the same swap. The numbers might surprise carburetor purists.
Lou Costabile tracks down Jeff Battaglia and his 1967 Ford Mustang Fastback GT 390 at the Muscle Car and Corvette Nationals in Rosemont, Illinois, where the car — restored over seven years at Platinum Custom Cars — makes its very first show debut. It’s not the Bullitt car, and nobody involved is pretending otherwise. This is a family restoration with its own story to tell. Watch to see how it all came together.
Flowmaster’s own breakdown of its muffler lineup tackles a question that trips up nearly every muscle car owner shopping for an exhaust upgrade: which series actually fits your car? With over a dozen options ranging from the raw, track-ready 10 Series to the daily-driver-friendly 50 Series, picking based on name recognition alone is a common and costly mistake. This video walks through exactly what separates each series — and why drone matters more than volume.
Tom Lembeck has spent decades building one of the more serious MOPAR collections around, so when he calls this 1970 Dodge Challenger R/T Convertible one of his favorites, it’s worth paying attention. The car wears a rare Triple Black specification — paint, top, and interior all finished in black — paired with the potent 440 Six Pack engine, and Tom has owned it since 1999. Lou Costabile sat down with him in Chicago to find out why.
The Horsepower Monster wraps up its three-part documentary on reviving a genuine Chrysler 426 Hemi — the engine Mopar fans still call the ‘Elephant’ — with the moment every rebuild ultimately comes down to: a dyno pull. After months of teardown, machining, and reassembly on one of the rarest engines Detroit ever built, the crew finally finds out whether their work paid off. The full dyno sheet is published alongside the video for anyone chasing the exact numbers.
Marspeed’s rundown of forgotten Dodge and Chrysler SRT models digs up five performance cars that history left behind — a turbocharged economy car, a German-flavored coupe, a Hemi-powered family wagon, and a full-size pickup running a Viper’s V10 under the hood. Each one carried real performance credentials in its day, yet all five have faded from the SRT conversation entirely. Some command real money today; others remain surprisingly affordable bargains. See which one you’d forgotten existed.
This 1968 Ford Torino GT arrived at the exact moment Ford finally stopped chasing the GTO and started genuinely competing, pairing aggressive SportsRoof styling with an available 428 Cobra Jet V8 that quietly embarrassed cars with flashier reputations. The redesign helped push the Torino to sales-leader status in its segment that year. Find out what made this underrated Ford one of the smartest muscle car buys of its era.
