The 3.8L turbocharged V6 engine that powered the Grand National and GNX was a unique creation in an era still recovering from the muscle car collapse. Unlike most performance cars of the time, it didn’t rely on a big V8. Instead, Buick engineered a torquey, boost-happy V6 that could blow the doors off cars with twice the displacement (1987 GNX #51 produced of 547 built - lead photo).

When Pontiac released the third-generation Firebird in 1982, many enthusiasts felt underwhelmed by the performance. As a result of tightening emissions restrictions, the top-trim 305ci V8 engine in the '82 Trans Am produced only 165 horsepower. These numbers would improve by the end of the third gen's run in 1992, but there was always a desire for an even more potent Firebird — one that could challenge GM's flagship Corvette. A startup called Street Legal Performance (SLP) partnered with Pontiac dealers to make this dream a reality. The resulting car was dubbed the SLP Firehawk, and only 25 were sold that year, making it an extremely rare vehicle today.

In the haze of underwhelming American cars of the 1980s, Buick—a brand long associated with elderly buyers and soft luxury—did something unthinkable. It unleashed a pair of performance monsters that tore through quarter miles and took down Corvettes, Mustangs, and even European sports cars. These were the Buick Grand National and the ultra-rare, legendary GNX (1987 GNX in lead photo).

The Buick Regal, introduced in 1973 (1978 Regal shown above), emerged during one of the most tumultuous eras in American automotive history. Stretching across the tail end of the muscle car era into the smog-choked malaise years, the first few generations of the Regal prioritized style, comfort, and luxury over outright performance. From 1973 through 1987, the Buick Regal became a case study in how government regulations, economic shifts, and changing consumer tastes could transform a car from a potential performer into a cruiser fit more for Sunday drives than drag strips.

When the U.S. military needs a vehicle, it's got to be rugged and tough. You're likely familiar with the HMMWV, also known as the Humvee, which would eventually become the primary "jack-of-all-trades" choice for a light four-wheel-drive military vehicle. But back in the early 1980s, the Humvee program was still in its infancy, and the vehicle that filled this role was based on something you should be equally familiar with: the Chevy K5 Blazer. This heavily-modified, diesel-powered Blazer — built by GM for a U.S. government contract — was known as the M1009 CUCV.

The 1969 Camaro is one of those cars that has seemingly been restored and resto-modded in every imaginable way. As a result of its widespread popularity, the '69 Camaro seems to appear at every classic car show, whether it's a carbureted original-style restoration or a pro-touring build with a modern fuel-injected V8. But for the Camaro owner who wants something truly unique, legendary custom shop Ringbrothers can build a car from the ground up with one-of-a-kind parts. This 1,000hp carbon-fiber-bodied Camaro, named "Strode," is a perfect example of what they do best.

Some Shelby Mustang tributes simply look the part. While others both look and act the part. This 1968 Shelby GT350 Mustang fastback clone both has the Shelby looks and is backed up by a prodigious Ford stroker small block V8 that packs quite a high-performance punch. There are also several enhancements to the pony car's suspension, wheels, tires, and brakes that are worth describing to let you know that you're not just looking at a nice-looking Shelby tribute.

NASCAR vehicles are designed to withstand truly extreme conditions. They lap the track hundreds of times at speeds in excess of 200 miles per hour, and in the event of a crash, must withstand the immense force of slamming into a wall at triple-digit speeds. However, once their time on the track is done, they're often retired to an unceremonious end. When Lance Smith of RaceRods found an old 1999 Craftsman Truck Series NASCAR chassis, he saw the perfect opportunity for a project. Grafting on a Chevy C10 body turned this into a mean-looking race truck for the street.

Losing a family member is a painful experience, but one which leaves us only one option: find a way to keep going. When Robert's brother in law passed away, he had been working on a '65 Mustang restomod project that was left incomplete, so Robert decided to finish the build in his honor. The result, as documented by YouTube channel AutotopiaLA, is this stunning 427ci V8-powered car with cantilever suspension and a long list of one-of-a-kind components.
