1968 Buick GS400 Concours Restoration Guide

The 1968 Buick GS 400 continued the second-generation GS formula with the 400 ci / 340 hp big-block and received updated exterior styling. The 1968 was a refinement year — the engine and basic architecture carried over from 1967 while the exterior received a fresh face. The landmark Stage 1 performance package was still one year away, but the standard 1968 GS 400 was already a capable 14-second car.
