There's no denying the pure cool factor of a late '70s Trans Am, especially one in the iconic black-and-gold paint scheme with snowflake wheels and that timeless hood bird graphic. However, its performance was another story. As a result of increasing emissions regulations, the T/A 6.6 was rated at only 200 horsepower in stock form, leaving many enthusiasts looking for new ways to make it as fast as it looks. The owner of this '77 Trans Am, Armen Pezeshkian, asked Los-Angeles-based restoration shop Vintage Motorworks to do just that, and the result is an 800-horsepower supercharged monster you have to hear for yourself.

After selling his Brazen Orange Metallic 2006 GTO, Brendon Vetuskey set out to build something more personal: a classic 1968–70 GTO that delivered vintage muscle car style without sacrificing real-world usability. Living in Los Angeles, that meant a car capable of enduring stop-and-go traffic, summer heat, and long drives - with cold air conditioning and dependable manners.

In nature, a hawk is a bird of prey that often hunts smaller birds. In the automotive world, the name Firehawk holds a similarly menacing reputation. The SLP Firehawk was originally released in 1992 as a high-performance package for the Pontiac Firebird Formula, and was available directly through Pontiac dealers under RPO code B4U. Over the next decade, the Firehawk package would continue to be available for the fourth-generation Firebird and Trans Am under RPO codes R6V (1993-97) and WU6 (1999-02). The following video from MotorWeek takes a look back at a pre-production prototype of the 1998 Firehawk, complete with an LS1 V8 and unique fixed headlamps.

At first glance, it looks like a refined late-’70s Trans Am - long hood, wide hips, Solar Gold paint glowing under the sun. But this one isn’t about nostalgia. This is what happens when a second-gen Trans Am grows up, gets real money thrown at it, and decides it’s done pretending.

Gearheads often remember the fast cars more than the movies or television shows where they appeared. In many scenes, cool cars outshine the actors, the television scripts, or the movie screen plays. The car chase scenes are often more compelling than anything else. Back in the days of Blockbuster Video, who doesn't remember renting the Bullitt video, sliding the tape into your VCR, and having the video cued up at the famous chase scene between the Charger and the Mustang fastback? Roaring engine sounds often eclipse a tv or movie score, if you want to get right down to it. And the sound effects of sirens blaring, cars crashing, sliding out, the General Lee jumping a stream, or burning rubber can even give a car guy or car gal goosebumps and an adrenalin rush right in front of a home or surround sound movie screen.

The late 1970s were a difficult time to be a performance car enthusiast. Following the OPEC oil embargo and the introduction of much more restrictive emissions requirements, American gearheads watched their favorite muscle cars wither away. The roaring big-block V8s of the early '70s were either discontinued or choked down to horsepower figures that seemed almost insulting. The EPA even blocked dealers from offering special engine-swapped models like the famous 427ci Camaros from Yenko, Baldwin, and Nickey. However, one Arizona-based Pontiac dealer found a workaround to produce a significantly faster 1977-80 Trans Am called the Macho Trans Am.

The 1970 Pontiac Firebird marked the beginning of the second generation of Pontiac’s answer to the Ford Mustang and the Chevrolet Camaro. Launched in the spring of 1970, the second-gen Firebird underwent a radical redesign that distanced it from the boxy aesthetic of the 1960s and embraced a more European-inspired, aggressive styling. Often hailed as one of the most beautifully sculpted American muscle cars of its era, the 1970 Firebird wasn't just about looks - it also packed serious performance credentials and helped Pontiac maintain its reputation as General Motors' performance brand.
