Pontiac built only 157 Ram Air IV Firebird hardtops for the 1969 model year, just 55 of them Trans Ams, and this freshly restored Firebird, pulled from The Brothers Collection, carries its original numbers-matching example paired with a 4-speed Muncie. Muscle Car Of The Week walks through what makes the RA IV’s idle and powerband so distinct from lesser Pontiac V8s. Watch to see one of the 102 standard Firebirds that got it.
ChrisFix sets out to settle a garage argument that never seems to end: does a performance exhaust actually make more horsepower, or does it just sound like it does? He tears into a full cat-back install, high-flow cats, an X-pipe, and straight pipes, and puts the results on a dyno before and after. Along the way, one unscripted moment involving his own mother became more famous than the horsepower numbers themselves.
By 1973, most of Plymouth’s real performance had already been regulated away — except for one engine nobody expected much from. Bud Lindemann puts this Cuda 340 through a full road test, and the stopwatch tells a story that surprised buyers who’d already written off the smog era. Watch to see exactly how quick a detuned Mopar could still be.
A weekend freeway cruise turns tense fast when a Hennessey-tuned C7 Corvette Stingray, pushing roughly 600 horsepower through an ECS supercharger, spots a patrol car mid-pull at triple-digit speed. The comment section has turned into a swap meet of near-miss stories from viewers who’ve had their own close calls at similar speeds. Watch to see how close this particular encounter came to going a very different way.
Urban Hillbilly Videos returns to its roots with this street racing compilation, tracing back to the old Kearney Street Cruise and the Highway 13 scene where the channel first built its following. Turbocharged and nitrous street cars — estimated in the 600 to 1200 horsepower range — go head to head while local authorities try to keep pace. It’s raw, unpolished footage from a scene that has largely gone underground, filmed by people who were part of it long before cameras showed up. Watch to see why fans are asking for more.
Detroit Speed dropped a blown modern HEMI into a 1969 Charger and built out 830 wheel horsepower, a number so high that TheSmokingTire had to publicly correct its own original estimate. Viewers immediately compared it to Roadkill’s notorious General Mayhem, just cleaned up and sent to finishing school. Watch the full build.
Tim Allen’s 1956 Ford pickup hides a genuine Chrysler Hemi under the hood, a build the shop dialed in across sixty-plus dyno pulls until it settled at 640 horsepower and 670 pound-feet of torque. It is a cross-brand swap that breaks every rule of Ford-versus-Mopar loyalty and turns a basic work truck into something that can embarrass purpose-built muscle cars. Watch to see exactly how this unlikely combination came together.
At Street Car Takeover OKC, a Procharged C7 Corvette running just 7 psi of boost — around 570 whp on a manual transmission — takes down a Nitrous Outlet Viper running without spray, all over a sandwich bet. The driver, known in the comments as Miss Stangkilr, wasn’t who the crowd expected to win. Watch the full Roll Race and see the bet get settled.
Alan Robinson’s Chevrolet Impala wagon weighs 4,720 pounds with its 26-inch street wheels and four JL Audio subwoofers still bolted in, runs a stock-bottom-end 6.0-liter engine at just 10 psi of boost, and still posts mid-11-second quarter miles at Hot Rod’s Drag Week. Getting to the line means swapping two of those 98-pound wheels for drag radials first. It wasn’t even the car Robinson planned to bring. Watch a wagon nobody expected to be fast prove exactly the opposite.
This twin-turbo, nitrous-fed Corvette showed up to Texas Invitational wearing two 88mm turbochargers that punch straight through the hood, backed by a 2,400-horsepower rating that its own team hasn’t even been able to confirm yet. A dead fuel pump capped boost at roughly 1,500 horsepower on this outing, leaving another 1,000 horsepower and a promised 200 mph pass still on the table. Fans can’t agree whether to call it a unicorn or a bull. Watch to see just how much of that power actually made it to the ground.
BigBlockNova468 hands the wheel of his freshly completed 500-horsepower big block Nova to a friend who normally drives a Lexus IS350 — and spends the entire clip visibly more nervous than she is. Commenters can’t decide what’s better: her composure behind the wheel of a solid-axle muscle car, or his face every time she blips the throttle. Watch to see how a Lexus driver handles 500 horsepower on the first try.
A stock Dodge Challenger Hellcat and a stock Dodge Viper lined up at the WannaGoFast half-mile event at Sulphur Springs Airport, Texas, with barely over a mile per hour separating their best trap speeds. Peter Dunn’s footage reignited the long-running debate over supercharged V8 power versus the Viper’s lighter, more aerodynamic chassis. See which car actually posted the higher number across multiple runs.
TFLtalk’s Emme, Roman, and Nathan rank their picks for the worst American cars of the last 40 years, and the comment section immediately pushes back. Viewers defend the AMC Gremlin’s bulletproof inline six, question whether a rebadged Suzuki or Daewoo even belongs on an American cars list, and make the case for AMC’s forgotten performance models. Watch the list, then see why longtime owners are not ready to accept it.
Richard Petty’s own 1970 Plymouth Superbird hadn’t turned a wheel on the road in over forty years — until Goodwood convinced him to drive it again. The winged, 200-mph NASCAR homologation special that helped make Petty’s name (and inspired Pixar’s The King in Cars) gets a rare public outing, engine roaring for the first time in a generation. Fans in Petty’s hometown of Randleman, North Carolina still stop him for photos to this day. Watch to hear what a real Hemi sounds like waking up after forty years.
Internal Combustion’s 4K walkaround of the 2017 Muscle Car and Corvette Nationals captures the Rosemont, Illinois show known for its Time Capsule survivor awards alongside concours-level restorations. The creator calls out Mopars, Boss 429 Mustangs, and Pontiac Firebirds as personal favorites, while one viewer argues the show is missing the average joe car altogether. MCACN’s indoor November format gives fragile, unrestored originals a weather-proof stage most summer shows can’t offer. Watch to see what an indoor survivor-focused show actually looks like up close.
