1978-1987 Pontiac Grand Prix

1978 was the first year a V8 was not the standard engine for the Grand Prix as the car lost 600 lbs. in an effort to improve fuel efficiency. However, its G-Body platform is a solid base to build upon with numerous parts and compatibility with several different GM engines.
