GM's G-Body architecture was introduced in 1978 and ran through 1988. While it had humble beginnings performance-wise, it provided the basis for iconic cars such as the Buick Grand National, Chevrolet Monte Carlo SS, and several NASCAR homologation specials such as the Pontiac and Chevrolet Aerocoupes. Today, the G-Body is an accessible platform for hot rodders that is capable of being a force to be reckoned with when combined with parts from the Detroit Speed Catalog.
