The 1967 Pontiac GTO introduced a larger 400 cubic-inch V8, replacing the earlier 389 and pushing performance further while adapting to evolving safety and emissions standards. Subtle styling changes included updated grilles, new taillights, and improved interior trim. The optional high-output engines and four-speed manual transmission continued to make the GTO a favorite among performance enthusiasts. As competition in the muscle car market intensified, the 1967 model balanced power, style, and everyday drivability.
