Blog: Bad to the Bone - ‘86 Grand National

This 1986 Buick Grand National is being offered by a seller in Port Elgin, ON for $30,000. This black coupe was only ever offered as such, and became famous in 1986 for its impressive 4.9 second zero-to-60 mph run, which rivalled contemporaneous top of the line Ferraris and Corvettes. 

The Grand National was named for the NASCAR Winston Cup Grand National Series. An off-shoot of the Buick Regal, running from 1978 to 1987, 91,229 Grand Nationals were produced in 1986.

Standard equipment in the 1986 Buick GN includes a Delco AM/FM cassette stereo, air conditioning, cruise control, and two-tone cloth upholstery. In 1986, Buick collaborated with MacLaren and added an air-to-air intercooler between the turbocharger and throttle body, and a new two-piece aluminium intake manifold for the Grand National’s 3.8 turbocharged V6 and attending 4-speed transmission. As a result, airflow was increased by 10%, with a rating of 235 horsepower and 330 lb-ft of torque that some experts have cited as being an understatement. 

This Grand National has been equipped with a 67mm Precision turbo, an SMC alcohol injection kit, 3” Hooker headers, 3.73:1 ring and pinion gears, a cast steel crankshaft, polished and ported 50 lb injectors, a Corvette Z06 style GM mass air sensor, custom American Racing wheels, and more.
