The 1984-96 C4 Corvette brought GM's flagship sports car into a new era of technology and refinement. Features such as the new "uniframe" construction, transverse leaf spring front suspension, sleek glass hatchback, and LCD gauge cluster made this Corvette feel modern, but the standard 230-horsepower L98 V8 left many enthusiasts wishing for more performance. GM would eventually respond in 1990 with the Corvette ZR-1, but back in the mid-80s, a company called Callaway Cars was quietly working on a twin-turbocharged C4 variant that would get the whole world's attention. The Callaway Twin Turbo Corvette was available through Chevrolet dealers under RPO B2K and offered European supercar performance at a fraction of the cost, plus a full factory warranty.

Few automobiles occupy a more fascinating corner of Corvette history than the five original 1963 Chevrolet Corvette Grand Sports.

They weren't production Corvettes with bigger engines. They weren't ordinary Sting Rays converted into race cars. And despite their familiar C2 silhouette, they shared surprisingly little with the Corvette sitting on a Chevrolet showroom floor in 1963.

Few cars invite closer inspection than a 1963-1967 Chevrolet Corvette. At any show, auction, or cars-and-coffee, someone will eventually lean over the passenger-side fender looking for numbers. There's a good reason: the difference between an ordinary small-block Sting Ray and a documented, original-drivetrain big-block car can be six figures or more.

This guide shows you how to read those numbers, what each one can prove, and where each one stops.

For Corvette C1 enthusiasts, a string of letters and numbers can reveal the beginning of a car's story.

Is that Corvette really a 1957? Where was it assembled? What does the VIN say about that 1955 Corvette's original engine?

Every August, the Monterey Peninsula becomes the center of the collector-car universe.

For a few glorious days, seemingly every road connecting Monterey, Carmel, Pebble Beach and WeatherTech Raceway Laguna Seca become an impromptu rolling car show. Ferraris mingle with Porsches. Prewar classics cruise alongside modern hypercars. Vintage racers thunder through the hills, and automobiles carrying seven- and eight-figure valuations suddenly seem almost commonplace.

Few things can spoil a drive in a classic Corvette faster than watching the temperature gauge climb toward the danger zone. That concern becomes even more important when there’s a heat-producing Chevrolet 427 big-block packed beneath the hood.

For Corvette enthusiasts, the name ZR1 means one thing and one thing only: the pinnacle of performance. Ever since the introduction of this racing-oriented option package in the 1970 model year, the Corvette ZR1 has been a car that raises eyebrows everywhere it goes — not just in America, but all over the world. It showed the automotive industry the best of what GM engineers had to offer, and in true "halo car" fashion, it was so expensive to produce that it constantly made the bean counters upset. More than 50 years since its launch, it's still surprising competitors and breaking records. Read on as we take a look back at ZR1 history and study every generation of the ultimate Corvette variant.

You don’t want your classic sitting in a museum, and you definitely don’t want it collecting dust in the garage while you wait on backordered parts from five different suppliers. You are building a machine meant to be driven hard. Whether it is a pro-touring Camaro with a Detroit Speed suspension, a restomod Mustang, or a street-brawling Chevelle rocking a Hurst-shifted Muncie, the engine is the heart of the build. And while LS swaps get a lot of the spotlight today, there is an undeniable, visceral authority to a traditional V8 breathing through a properly tuned high-performance four-barrel carburetor.

Most car enthusiasts are familiar with the name ZR1, whether it's from the original run as a high-performance variant of the 1970-72 Corvette C3 or its continuation during the C4, C6, C7, and C8 Corvette generations. But far fewer enthusiasts know about the ZR1's much rarer sibling, the Corvette ZR2. This hardcore, big-block-powered package was offered only during the 1971 model year, and a total of just 12 Corvette ZR2s were ever built — ten coupes and two convertibles. Today, a surviving '71 Corvette ZR2 can sell for over a million dollars.

Some cars are built to turn heads. Others are built to make history.

For the 110th running of the Indianapolis 500 presented by Gainbridge on May 24, Chevrolet’s new Corvette ZR1X will do a little of both as it leads the 33-car field to green at the Indianapolis Motor Speedway.

And honestly, could there be a more fitting choice?
