John Hennessey’s shop strapped a Shelby GT350R to the dyno wearing its new HPE850 supercharger package, running on Shell V-Power 93 octane, and posted a pull that added 311 rear-wheel horsepower and 193 lb-ft of torque over the car’s naturally aspirated baseline. The resulting graph, a dual-scale readout where the horsepower and torque curves cross around 7,400 rpm, briefly confused viewers before the final number sank in. Watch the pull to see what boosting a flat-plane-crank Voodoo V8 actually looks like on the rollers.

GRIZZ isn’t a real 1970 Superbird – it’s Joel Highsmith’s modern custom tribute build, and it’s chasing numbers no factory aero car ever touched: over 1,000 rear-wheel horsepower and a 194mph top speed. Gearhead Flicks’ feature has drawn nearly 725,000 views, plus a sharp-eyed comment correcting the car’s own naming and a wild detour involving a theft and recovery. Find out where GRIZZ is racing next.
A mildly modified 2004 Dodge SRT-4 takes on a four-speed, 383-powered 1965 Plymouth Belvedere in a street matchup that should have favored the turbocharged compact. More than a decade of comments still argue over who really won, split between Mopar loyalists and turbo-four believers. Watch to see whether raw displacement or forced induction wins the day.
Hagerty Executive Editor Stefan Lombard opens with a dare: you really can’t go wrong with a Chevelle, true or false? What follows is a rundown of exactly where Chevelle buyers get burned, from cloned SS badges to rust hiding under a straight-looking floor pan. Watch before you go looking for one yourself.
Owner Jeffrey Filz grew up two blocks from the Kenosha plant that built this 1970 AMC Javelin SST Mark Donohue Signature Edition, and the comments below Lou Costabile’s video turn up an even wilder story: a commenter’s father, a former Spitfire pilot, briefly owned one himself. Watch the full walkaround and engine start.
Road Test TV lines up two of Chrysler’s rarest factory muscle cars, a 1968 Plymouth Road Runner and a 1968 Dodge Super Bee, both fitted with the legendary 426 Hemi, for a naturally aspirated quarter-mile grudge match. The comments reveal an audience less interested in who wins than in celebrating two genuine Mopar icons running clean 11-second passes. Watch to see how two of Detroit’s most feared engines settle a very friendly family argument.
Pontiac officially rated the 1969 GTO Ram Air IV at 370 horsepower — and deliberately lied about it. This episode of Muscle Car Of The Week features a rare Ram Air IV 400, four-speed GTO convertible from The Brothers Collection, loaded with options seldom seen together. The comments reveal why Pontiac’s real output was closer to 420-430 horsepower, and how an internal weight-to-power directive, aimed at dodging insurance rate hikes, kept the true number off the window sticker. Watch to see the car behind the number that was never supposed to be accurate.
When the California Highway Patrol specified a pursuit car in 1961, the requirement was brutal: 100 miles per hour sustained for a full hour in 100-degree heat, without failure. Jay Leno’s Garage brings in a fully restored 1961 Dodge Polara built to exactly that spec, courtesy of restorers Morgan Yates and Dave Skaien of the Automobile Club of Southern California. The comments add real memories from CHP families and desert truckers who lived through that same era. Watch to see what it actually took to build a car for that job.
A third-generation Camaro doesn’t usually get much respect in muscle car circles, but one owner’s IROC-Z, featured here by The Drive, might be the car that changes that. Built with years of restraint instead of loud mods — factory badging intact, no stripe graphics, only the wheels giving it away — it’s what the crew calls the absolute perfect version of a car most people already wrote off. The comments turn into a flood of childhood memories about parents’ IROCs and Z28s. Watch to see what makes this one different.
Ford built the Boss 351 for exactly one model year before discontinuing the entire Boss lineup — just 1,806 were made. Jeff Ball’s example, finished in Ford’s short-lived Grabber Lime and shown at the Muscle Car and Corvette Nationals in Rosemont, Illinois, is the rare kind of Boss most enthusiasts have only read about. Under the narrow-windowed 1971 bodywork sits a 351 Cleveland V8 that some owners call the quickest of the three Boss Mustangs. Watch to see why this one-year-only Ford still divides opinion decades later.
From Steve McQueen’s Bullitt in 1968 to John Wick in 2014, the Dodge Charger has been Hollywood’s go-to car for spectacular on-screen destruction, and this compilation pulls together seven of its most memorable on-camera deaths. Along the way it traces how practical stunt work evolved from the golden age of Cannonball and Dirty Mary Crazy Larry through Tarantino’s deliberate throwback in Death Proof. Even the comments can’t agree on which Charger send-off hurts the most. Watch to see which seven films made the cut.
Street Car Video brings a Corvette ZR1, a built Cadillac CTS-V, a turbocharged Camaro, and an 850-horsepower Hellcat to the same meet — and the real story ends up being the turbocharged trucks that kept pace with all of them. Viewers call it proof that horsepower doesn’t care about body style. Watch the full lineup to see just how close it actually got.
Its billed as a barn find, but there isnt a speck of dust or a single flaw to be found on this 1967 Mustang fastback nicknamed Helleanor, a claim skeptical viewers might want to take with a grain of salt. Underneath sits a 402 cubic inch small-block pushed by twin turbochargers to a claimed 3,000-plus horsepower, running low-4-second eighth-mile passes while reportedly holding back another 1,500 horsepower in reserve. Between the staging precision and that unmistakable turbo whistle, its easy to see why this ones racked up over 1.6 million views. Just how much is this car really capable of?
This 1967 Chevrolet Camaro carries build number N100001 — the very first unit off Chevrolet’s Norwood, Ohio assembly line. Along the way it was stripped down and turned into a race car, a fate that erased the history of countless early Camaros before it. What saved this one was a single decision: whoever converted it kept the original parts instead of scrapping them, making a true, numbers-matching restoration possible decades later. Watch to see how a factory-first Camaro survived its own history.
VisioRacer’s countdown of the 15 best-sounding V8 engines has racked up 3.7 million views, and the comments turn into a timestamp-by-timestamp debate over a supercharged Hellcat whine, the Shelby GT350’s flat-plane Voodoo V8, a 6.4 Hemi, and even a surprise Volvo entry. Watch the full list and see where your favorite lands.
