Over the past four decades, General Motors has proven itself a modern day warrior. The company literally OWNED the '50s and '60s, and no matter how much corporate bean counters tried to quell its spirit of performance, true gearheads ALWAYS kept the flame lit. And I'm not talking about Corvettes or the incredible Cadillac V-Series. I'm talking about cars that are fast, fun and highly attainable. In the early 21st century, the guys at Pontiac worked with GM's Holden division to send world-class muscle to American shores. During the stuffy '70s the venerable Trans Am soldiered on with big displacement motors and flashy good looks. In the mid-'90s, Chevrolet's visionary Impala SS brought a new sense of cool to the full-size segment. And in the '80s, it was this car: Buick's bad-to-the-bone Grand National that proudly separated the winners from the losers. All black, all business and so sinister even your shut-in grandmother knows it means trouble, this prim and polished coupe backs $31K worth of V6 power with a modified drivetrain and custom suspension!


Capitalizing on the success of winning NASCAR's 1981 and '82 Manufacturer's Cups, Buick kicked off the Grand National legacy by introducing a specially tweaked version of their 1982 Regal. However, it wasn't long until GM's conservative luxury crew assumed the full identity of renegade performance division by slathering black paint over highly modified G-Bodies that featured unique and menacing aesthetics. This coupe's wet-looking coat of GM code 19U Black highlights original sheetmetal that's both crisp and sharp. The car's vertical panels center straight surfaces in even gaps, showing no signs of damage or accident repairs. And, topped by great looking, factory-correct trim, the finish on those panels is every bit as glossy as it is deep.


Speaking of survivors, and GM's core strengths, if anyone ever creates an ultimate engine survivors list Buick's stalwart, 231 cubic inch V6 will surely be at the top. Introduced as the Fireball, and eventually renamed the 3800, its early '60s design was sold to Kaiser, bought back by General Motors and, with the help of turbos, superchargers and continuous improvements, would remain one of the company's core powerplants until the turn of the century! The professionally built sixer behind this coupe's Vader-like grille is founded on a new block that was magnafluxed, sonic-tested, squared, honed, bored .020 and fitted with CNC-ported Champion Racing heads. Inside that block, A SCAT stroker crank combines with billet, hand-machined rods, machined and coated Ross Racing pistons and a Comp hydraulic roller cam to provide smooth inertia. Combustion is created when 8mm AC Delco Premium Silicone wires bump Morel roller rockers, Morel pushrods and Morel lifters. A steady amalgamation of oxygen and fossils is provided by a K&N air filter, a 70mm Accufab throttle body, a ported and matched intake, Alkycontrol Methanol Injection and 60# fuel injectors. And coated headers, a PTE high-flow intercooler, fabricated air tubes and a TA Performance oil pump keep everything lucid and cool. All those carefully calculated improvements are, with the help of a TurboTweak chip, good for a universally impressive 550 dyno-proven rear wheel horsepower. And items like ARP bolts, ARP studs, Cometic gaskets, coated engine bearings and a Cloyes roller timing set ensure everything works in unison to provide invigorating and equally terrifying acceleration.


With that kind of power on tap, it should come as no surprise that the bottom of this Buick features a host of noteworthy upgrades. Behind the raucous engine, a custom-programmed Four C's automatic transmission makes good use of a SCAT flywheel, a 3,500 RPM non-lockup stall and 200R4 billet internals. That gearbox twists torque through a billet yoke, a heavy duty driveshaft, heavy duty U-joints and a proven Currie 9-inch, which is fitted with beefy, 3.53 gears. Factory power steering rides between QA1 Street Control Arms and adjustable QA1 coil-over-shocks. Out back, adjustable QA1 trailing arms compress two more QA1 coil-over-shocks. Power-assisted stops are provided by a combination of big Wilwood calipers, drilled and slotted rotors and 11-inch GM drums. Charred dinosaurs float in to rowdy Pypes Race Pro mufflers. Power meets pavement through Budnik X-Series Grand National wheels, which spin 225/45ZR17 BF Goodrich g-Force Super Sports in front of 275/40R17 Mickey Thompson ET Street Radials. And everything, from the car's beefy sway bars and billet flywheel cover to its notched frame and RJC oil pan, is well planned, well detailed and ready for action.


Inside this awesome street bruiser you'll find a correct Gray and Black interior that's virtually spotless. Typical Buick fashion dictates more comfort than sport, but then, that's what GM's entry luxury brand has always been about. And naturally, that means this Grand National is loaded with all the features you'd expect including power windows, power locks, climate control, cruise control and a tilt steering wheel. In front of that wheel, leather-wrapped SCAT PROCAR buckets provide much more support than factory fodder. Opposite those seats, factory gauges inhabit a blocky dash that's free of warps and cracks. Below that dash, a factory console frames an elegant factory shifter. Behind the passengers, a carpeted trunk seems big enough to abet weekend travel. And, because increased safety is essential at this level of performance, everything is wrapped in a full roll cage.


Although Buick's official, Grand National-specific “K” code was never actually used when GM assembled cars, authentic Grand Nationals ARE VIN-coded for turbo engines. Here's a detailed breakdown of this sinister coupe's VIN:

* 1 -- Manufactured for the United States
* G -- Manufactured by General Motors
* 4 – Buick Motor Division
* G – G-Body platform
* J – Regal / Regal Grand National
* 1 – 2-door coupe
* 1 – Manual belt restraint system
* 7 – LC2 3.8 liter SFI intercooled turbo V6
* 9 – Check digit
* H – 1987 model year
* P – Assembled in Pontiac, Michigan
* XXXXXX – Serial number


* Restoration receipts
* Engine specs
* A dyno sheet
* Component manuals

Nobody scoffs at Buick's legendary Grand National. Between old school NASCAR DNA and the ability to whip pretty much any street challenger, the car gets big respect and much admiration. With $31K in engine receipts alone, this incredible G-Body is an incredible bargain. And you can pretty much bank on the fact that the car will grow in value as it and its buyer base continues to mature. So, what are you waiting for? Grab this beastly Buick and enjoy one of the nicest Grand Nationals on the planet WHILE it appreciates!
