Mercury Racing spent decades building engines for boats before it decided to sell one for cars. The SB4 7.0 starts life as a GM LS7 block and then gets something no factory small block ever had: dual overhead cams, 32 valves, an 11.7:1 compression ratio, and an 8,000 rpm ceiling, all rated at 750 horsepower on 91-octane pump gas. It ships turn-key for 32,995 dollars. Read on to find out what it actually takes to make a small block spin that high.
Pontiac named this muscle car after a TV punchline and painted the first 2,000 examples a color buyers weren’t allowed to refuse. Loud stripes, a towering spoiler, and a Ram Air V8 under the hood made it impossible to miss on the street in 1969. Only 6,833 left the factory that year. Take your best shot at a caption before reading the story behind it.
One second a car is cruising in freeway traffic, the next its tire is bouncing across multiple lanes with zero warning. Nobody in the clip sees it coming. Here’s what actually causes a wheel to separate at speed — and why it endangers a lot more than one car.
Engineering Explained gets inside Chevrolet’s Performance Build Center at the Corvette factory in Bowling Green, Kentucky, where the naturally aspirated LS7 and supercharged LT4 come together by hand. One engine chases power through raw displacement, the other through forced induction, and both end up in very different 2015 performance cars. See exactly what separates a 505-horsepower big-block philosophy from a 650-horsepower supercharged one.
Dodge built the only all-wheel-drive American muscle coupe ever sold, and then gave it a V6 instead of a Hemi. The 2017 Challenger GT made 305 horsepower, started at $33,395, and sent up to 38 percent of its torque forward only when it decided the situation called for it. That combination confused a lot of shoppers. It also answered a complaint Dodge had been hearing from buyers in snow states for years.
Almost nobody ordered a 1966 Chevy II Nova wagon with a V8, which is exactly why one turns heads now. The same sharp restyle that reshaped the whole Nova line for 1966 applied to the wagon too, and buyers could order a 327 rated as high as 275 horsepower in that body. There was one engine Chevrolet refused to put in it. Read on to find out which one, and why a V8 wagon is the rarer find today.
This 1968 Chevrolet Camaro looks street-legal at a glance — working lights, turn signals, a full interior — but the tubbed rear end and fabricated chassis underneath tell a different story. Under a polished Pro-Filer induction setup sits a big-block build engineered for the strip, not Main Street. Read on to find out what separates a genuine pro-street Camaro from anything Chevrolet ever built.
A recent look at search data from classiccars.com found one vintage nameplate pulling ahead of every rival by a wide margin. The Ford Mustang’s dominance traces back to a launch day that moved tens of thousands of cars almost instantly, followed by sales that topped a million units within its first couple of years. Its continuous production since 1964 has kept the name in front of casual fans in a way few muscle car rivals ever managed. Read on to find out how the numbers broke down state by state.
One photo, one mystery car, zero easy answers. This guessing game challenges muscle car fans to identify the year, make, and model of a classic ride using nothing but a single shot. Some details give it away fast; others are designed to trip up even lifelong gearheads. Think you know your metal? Take your best guess before reading on.
This restomod 1955 Ford Thunderbird trades its original 292-cubic-inch V-8 for a blown 396 Chevy big block breathing through a 6-71 supercharger poking straight through the hood. Underneath the red paint and whitewalls sits a Mustang II front end, a Ford 9-inch rear, and modern disc brakes — all wrapped around the body that nearly didn’t happen. Read on to find out what a $2,944 personal luxury car from 1955 has in common with a 1,000-plus-cubic-inch-equivalent street machine.
Between 1959 and 1962, Oldsmobile redesigned the Rocket 88 practically every single year — new frames, new suspensions, and an American first buried inside the lineup that most shoppers walked right past. The Starfire’s console-mounted shifter changed how automatic transmissions were packaged industry-wide. Read on to find out which year brought the biggest structural change, and why the Starfire deserves more credit than it usually gets.
The 2017 Corvette Grand Sport brought 460 horsepower and the Z06’s wide body for around $66,000. The refreshed Porsche 911 Carrera S made 420 horsepower from a twin-turbocharged flat-six and cost closer to $104,000. On the spec sheet that looks like a rout, and then the test results came back and refused to line up with the numbers. Here is where each car actually wins, and why the price gap does not settle it.
Most concept cars end up crushed or crated. The first 2007 Shelby GT ever built spent years as a working development mule instead, wearing a Whipple supercharger, Baer brakes, and 20-inch wheels while Shelby figured out what customers would eventually be able to order. It showed up at Barrett-Jackson Las Vegas as Lot 737 with 9,360 miles on it. Here is why that particular Mustang mattered more than its horsepower number suggests.
Between 1969 and 1974, Jaguar’s E-Type went through more change than any four-year stretch in its history — detuned engines for U.S. emissions rules, a completely new V12, and a dozen ultra-rare lightweight racers built alongside the roadgoing cars. The Series III’s 5.3-liter V12 turned the E-Type into a genuinely different machine, capable of 135 mph and a 14.82-second quarter mile. Read on to find out what separates a Series II from a Series III, and why twelve specific cars from 1963 and 1964 remain the most valuable E-Types ever built.
Long before car memes existed online, muscle car culture was already built on the same kind of good-natured ribbing — chalked onto staging lanes, printed on bumper stickers, or scrawled across club newsletters. The photo above is just the latest version of a tradition that’s been running for as long as these cars have existed.
