This 1987 Buick Grand National was repainted and modified by the selling dealer with a 6.2-liter LS3 V8 crate engine and a B&M 4L60E Street/Strip four-speed automatic transmission with a 2,800-rpm torque stall converter. It rides on factory-style 16″ cross-lace wheels with adjustable QA1 coilovers, QA1 sway bars, and a Wilwood front big brake kit. Further build highlights include a Holley accessory drive system, Hedman headers, a Hooker stainless-steel exhaust system, an aluminum radiator with dual electric fans, a transmission cooler, Vintage Air air conditioning, and Dakota Digital gauges. Finished in Black over Black and Sand Gray cloth, the car also features GNX badging, composite wheel arch flares, front fender vents, a sunroof, a rear spoiler, a Delco cassette stereo, and cruise control. This Grand National is now offered in Texas with the owner’s manual, a clean Carfax report, and a clean Michigan title.
