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, not to sell to the public, and that’s exactly what makes it so special. The factory rated it at 425 horsepower, but nearly everyone who’s put one on a dyno says that number was conservative by a wide margin. Fewer than 10,000 street versions were built across just six model years, which is why a numbers-matching Hemi car commands serious money today. This is the engine that earned the nickname ‘Elephant’ for a reason.
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.
Twin 88mm turbochargers mounted right in the grille tell you everything you need to know about this Camaro’s intentions. Turbos of that size are built for big-block combinations chasing serious horsepower, not weekend cruising. Here’s what that kind of setup usually means for a first-gen Camaro built for the strip. Whoever built it clearly wasn’t chasing subtlety — they were chasing serious quarter-mile numbers.
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.
A brand-new Dodge Demon — Dodge’s 840-horsepower, factory drag-ready Challenger — gets delivered in Amarillo, Texas, and the crowd around it turns into its own story. Commenters split between outrage at strangers touching a sold car and celebration for the buyer’s family. Watch what happens when one of the rarest muscle cars ever built shows up at a small-town dealership.
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.
Chrysler engineer Gary Romberg spent 1969 and 1970 wind-tunnel testing the shape that became the Dodge Charger Daytona, adding an 18-inch nose cone and a roofline-clearing rear wing that combined for 1,800 pounds of downforce. The result was a 0.28 drag coefficient, a first 200 mph NASCAR lap, and a win at Talladega – all from a car Dodge built only 503 examples of. These photos put that legend side by side with a modern Hellcat.
A stroked LS3 and a 10-mile traffic jam outside the California/Nevada line are what it took to strand Project Orange Krate, a 1971 Camaro with a project-car pedigree that traces back to the long-defunct Camaro Performers magazine. It’s second in magazine-build longevity only to the legendary Project X. Running out of gas mid-desert on I-15 turned a good weekend at Holley LS Fest West into a lesson every pro-touring builder eventually learns the hard way: horsepower changes your fuel math more than your gauge admits.
