Launched in 1967, when GM->ke2320 decided to give Pontiac->ke70 a piece of the pony car market action by sharing the Camaro's->ke248 F-body platform, the Firebird became an integral part of the muscle car->ke507 wars within a couple of years. 1970 saw the introduction of the second-gen model, which included the most brutal Firebird ever built. In its range-topping trim, the coupe came with a 7.5-liter V-8 under its hood and more than 360 horsepower routed to the pavement. With Pontiac out of the automotive scene for more than four years as of October 2014, the Firebird is one nameplate we wish was still around. Fortunately, the legacy of the early cars grew stronger the past four decades, and first- and second-gen Firebirds have become sought-after collectibles.

While some examples are being restored and taken care of by enthusiasts, other Firebirds->ke4427 are joining the restomod ranks by receiving modern underpinnings and amenities. Which brings us to this 1970 coupe->ke141 that was auctioned off for $87,000 by Mecum Auctions. It's black, mean and powered by a twin-turbo, 7.8-liter V-8 that's ready to rip the tarmac off a drag strip under full throttle. Check out the details after the jump.

Pontiac Firebird Resto Mod in detail

Built by All Speed Customs, this 1970 coupe gives the Firebird a whole new life. Although most of the original body panels are still in place, the shell has been modified to include a host of aerodynamic parts, including a front splitter, a new rear bumper with an integrated diffuser, and revised side skirts. The front fascia also gained a bespoke grille and a unique hood that incorporates two custom air intakes. The exterior is rounded off by a set of black-painted, Forgiato Ritorno wheels shod in performance tires and a gloss-black paint job with a dark-gray stripe from hood to trunk.

The interior was revamped in a similar fashion, with nearly every detail finished in black. The all-leather seats are highlighted by while dual stitching with five-point harnesses added for extra safety. The cabin also features a custom center console, an aluminum dash plate, billet door handles and bespoke floor mats. Other goodies include original Trans Am gauges, a Vintage Air Sure Fit climate control system, and

keyless ignition.

Things get ever wilder under the hood, which hides a 7.8-liter, V-8 engine and a pair of 66mm Bullseye turbochargers. In fact, nearly every component has been updated to modern standards, with All Speed Customs adding a bespoke air-to-air intercooler, stainless manifolds, new plumbing and custom stainless-steel headers. The mill mates to a Rockland Tranzilla T56 6-speed transmission and a Ram twin-disc clutch built to handle the horsepower. Speaking of horsepower, All Speed Customs says this Firebird has 1,200 horsepower at its disposal, making it more powerful than most modern-day supercars.

For $87,000, this Firebird is one heck of a bargain!
