The Buick Grand National Was Truly a Factory Performance Hot Rod

he Buick Grand National, particularly the 1987 model, is celebrated for blending classic American muscle with cutting-edge technology (back in the day), resulting in a car that redefined performance in the late 1980s. The 1987 Grand National is best known for its turbocharged 3.8L V-6 engine. However, Scott Floyd of Phoenix, would soon have other ideas for power.

The car was initially purchased from the proverbial little old lady from Ohio, with the odometer showing 30,000 original miles, and it still sports its original black paint to this day. Unfortunately, shortly after the purchase, the V-6 “spit” a rod out, and then the decision was made to “go for it.” The story goes that the ashtray had a boost gauge, possibly implying the car’s true ancestry. Scott and A.J. Schwichtenberg of Goodfellows Classic Cars then collaborated on their next step. Schwichtenberg brought the 1987 Grand National Performance specs up to modern-day standards—a 10-second streetcar.

The first step was to overcome the now-defunct V-6. In its place, a brand-new Chevrolet Performance LSA V-8 was added. It’s the second generation of GM’s Gen IV small-block engines. It is a supercharged 6.2L V-8 capable of delivering an impressive 556 hp and 551 lb-ft of torque. Exiting all the spent gases is a custom exhaust system by Goodfellows based on 3-inch stainless steel tubing and a pair of SpinTech mufflers. This engine is known for its robust construction and advanced technology, featuring an integrated supercharger that ensures strong performance across a wide rpm range. Schwichtenberg added a crossflow aluminum radiator, oil and trans cooler, and electric fans from Performance Rod & Custom to the engine compartment, as well as custom-made power steering and overflow cans. Remember the LSA is supercharged and now employs a very accommodating Wagner serpentine belt system to handle the charging, steering, and A/C chores. Schwichtenberg cut down a 10- to 8-groove serpentine belt to work with the pulley configuration that now resides on the front of the LSA. Corralling all the 600-plus horsepower and getting it to the ground are Nitto rubber with rear drag radials on Grand National–style 18-inch wheels.

What distinguishes the 1987 model from earlier Grand Nationals is its significant enhancements in both performance and refinement. Compared to its predecessors—particularly the 1984-1986 models—the 1987 Grand National showcased improvements. To the already-robust suspension, Goodfellows has modified the stock frame to accept tubular control arms, Wilwood spindles, and 13-inch drilled-and-slotted rotors with six- and four-piston calipers in the front and rear. The front suspension also features Strange coilover shocks, a new front sway bar, and a NASCAR quick-ratio steering box. In the rear is a Strange 9-inch rearend with accompanying 31-spine axles and a 3.50 gear.

The exterior design of the 1987 Grand National maintains the aggressive, stealthy look that the Grand National nameplate is known for. The iconic all-black coloration, paired with subtle yet menacing styling cues such as the front air dam and rear spoiler, gives it a distinctive presence on the road. The 1987 model was produced in limited numbers during its production run, which adds to its allure today for hot rodders.

Inside, the 1987 Buick Grand National delivers an equally impressive experience. The interior features supportive bucket seats upholstered in a plush, darker material that complements the exterior aesthetic. The driver and passenger seats are designed to provide comfort for long drives while securing occupants during spirited driving.

Other noteworthy features include the available digital instrument cluster, which, for the day, offered a bold, modern look compared to standard analog dials. Optional amenities include air conditioning and an AM/FM stereo, making the Grand National a performance machine and a comfortable daily driver. The instrumentation on Scott’s Grand National does feature Dakota Digital VHX and now a modern Alpine touch screen stereo. At the same time, the steering column is stock with an aftermarket wheel that is slightly smaller in diameter and features some Schwichtenberg handiwork, rescuing the original V-6 horn button. The center console is original, but Schwichtenberg did fashion some of his handiwork to make the original shifter work with the new 4L75E trans with an Schwichtenberg-installed aftermarket converter and a PRC cooler. The original factory A/C was retained with a modern condenser and evaporator now used. This effort, as well as the car’s fresh wiring, was performed by Schwichtenberg at the shop.

Much of the interior is original, including the seating, door and kick panels, headliner, and carpeting. Remember, it was a well-cared-for, low-mileage, one-owner car. The plush carpeting in the 1987 Grand National extends throughout the cockpit, providing a sense of luxury that was somewhat uncommon in performance-oriented cars of the era. This premium touch is complemented by soft-touch materials on the door panels and dash. Additionally, the cabin is equipped with quality soundproofing, contributing to a quieter ride while cruising, which contrasts with the vehicle’s performance persona.

The overall theme of the 1987 Buick Grand National’s interior echoes the idea of understated athleticism, reflecting the external aggressiveness without veering into overt opulence. Its combination of performance, technology, and design has made it a darling in the automotive world, and this specific model year remains a symbolic representation of Buick’s prowess during the 1980s.

Ultimately, the 1987 Buick Grand National embodies a unique intersection of innovation and style, making it a standout among its peers. Scott’s LSA supercharged V-8 now offers twice the horsepower and torque that the original Grand National may have had, but it also offers twice the punch with its 10-second quarter-mile blasts. Hot rodders continue to be drawn to the Grand National for its historical significance, distinctive characteristics, and thrilling drive, and given what Scott has accomplished, we believe he has set a new standard.
