1987 Buick Grand National
Parts Pictorial

    The drivetrain has been put through a major overhaul in preparation for the next level of performance. Currently, the engine and transmission are back in the car. A few more minor items have to be addressed yet. The following pictures, with their descriptive links, present components and modifications the car has to improve the ¼ mi. performance and overall handling. In general, I'm going by suggestions from Red Armstrong of Quad Air but many of the changes are similar to the modifications presented on the Buick Turbo Regal Recipe Page .
