Saabkyle04 gives the 1970 Ford Mustang Mach 1 the same in-depth, first-person treatment he brings to everything from vintage Impalas to Lamborghinis — start-up, exhaust note, and a full walkthrough of what changed when Ford swapped in the 351 Cleveland V8. One commenter’s memory of staring at his brother-in-law’s Mach 1 for hours in 1972 says as much about this car’s legacy as any spec sheet could. Watch the full review to hear that exhaust note for yourself.
A 1968 Dodge Charger body, a twin-turbo Viper V10, and a Corvette chassis underneath — this Swedish-built hybrid took five years to complete and reportedly left Jay Leno speechless. Street-legal and rated around 1,000 horsepower, it’s the kind of build that mixes three unrelated platforms into something none of their original manufacturers ever intended. Commenters keep coming back to one detail above all else: the sound. Watch to hear why.
International Dyno Authority walks a rough-idling 1969 Camaro Z28 through a full carburetor tuning session, chasing a damaged choke plate, float adjustments, and jetting changes one dyno pass at a time. The result: a 20 percent horsepower gain and 12 percent torque gain, entirely from tuning — no new parts required. It’s a clear, step-by-step reminder of how much power a poorly adjusted carburetor can quietly hide.
A Texas tuning shop put a bone-stock 2017 Camaro ZL1 and its brand-new 10-speed automatic through a real 0-180 mph pull, and the data logger caught it still upshifting at the top end. Viewers argued over everything from the fuel gauge to a short-shifted launch. Hennessey teased something far more extreme was coming next. Watch the full run to see it.
A countdown of the six largest production engines General Motors ever built draws exactly the kind of comment section you would expect from a genuinely technical audience, including one commenter’s joke that working on a 496-cubic-inch big-block requires a mandatory cigarette dangling from the mouth at all times. Beneath the humor sits real engineering history, including a detailed explainer on how GM’s divisions once each built their own competing V8 platforms. Watch the full countdown to see which engines made the cut.
Doug Cline drove his twin-turbo, roughly 3,000-horsepower big-block Camaro over 1,300 miles to reach Rocky Mountain Race Week. On the event’s final day, fuel buildup off the line turned into a 190-mph excursion off the racing surface, and a split-second decision not to pull the chutes ended up filling both turbochargers with sand and gravel. See exactly how a week of extreme mileage and extreme horsepower came down to one costly moment.
Chrysler built the 426 Hemi to win NASCAR races and had no intention of selling it to the public. A homologation rule forced the company’s hand, and for six model years a lightly civilized race engine was available over the counter to anyone who could afford the option and the insurance. Here is what made the Elephant so effective, what the 425-horsepower rating really hid, and why 1971 was the end of it.
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.
210 episodes into covering the Brothers Collection, Muscle Car of the Week finally ranks the convertibles — pulling from a 1967 Mustang K-code, a 1964 Plymouth Satellite 426 Wedge, a fuel-injected 1959 Corvette, and a 440 Six Barrel ‘Cuda in Tor-Red. Each car represents a different era and manufacturer’s approach to open-top American performance. The comments are already split over which one deserves the top spot. Watch to see the full lineup and decide which convertible you’d pick.
This 1989 Chevrolet Camaro IROC-Z convertible has covered just 7,630 original miles in the hands of a single owner who kept it in a climate-controlled garage for twelve years. Chevrolet built only 3,940 convertibles that year, making this a genuinely rare, well-documented survivor from the final seasons of the IROC-Z badge. The listing lays out the VIN, mileage, and history in detail rare for a car this age. See the full walkaround and find out what makes this one worth a serious look.
One supercharger wasn’t enough for this 1958 Chevrolet Biscayne — its builder stacked three of them under the hood of a full-size platform that was never meant to carry this kind of hardware. The result is a sleeper build so over-engineered that even seasoned viewers do a double take. Comment section reactions range from admiration to a warning about getting carried away with power numbers. Watch to see exactly how a triple-supercharged setup comes together on a car this unexpected.
Every carbureted muscle car ever built ran on a fuel-delivery system with no computer, no sensors, and no electric pump doing the metering — just air pressure exploiting simple physics. This explainer breaks down exactly how a venturi, float bowl, and calibrated jets work together to keep an engine fed at idle, cruise, and wide-open throttle. It’s the same principle behind every Holley, Quadrajet, and Thermoquad ever bolted to a big-block. Watch to see why a technology this simple ran the automotive world for most of a century.
Gearhead Garage’s Jason breaks down eleven specific modifications that commonly hurt a classic muscle car’s performance, safety, or value — from rear disc brake conversions to flex fans to spooled rear differentials. The comment section turns into its own confirmation hearing, with longtime owners describing which of these mistakes they made on their own builds and what it cost them to fix. Watch to see the full list and decide how many you have made yourself.
Carburetor or fuel injection — which one actually makes sense for your build? Summit Racing’s Dave breaks down 2-barrel, spreadbore, and race carburetors against modern EFI, and the comments below are full of real builders working through the same decision on their own cars. Watch to see where the technical trade-offs actually land.
A 1969 Charger Daytona and a modern Charger Hellcat parked nose to nose look like a fifty-year technology gap, and in most respects they are. But the older car still holds an aerodynamic claim the newer one cannot match, achieved with an 18-inch nose cone, a wing tall enough to reach clean air, and a wind tunnel program run on a scale model. Only 503 were built, all for a single purpose: winning at 200 mph.
