This seemingly stock 1968 Pontiac GTO harbors a formidable secret beneath its exterior, boasting an enhanced suspension and custom interior. The engine, professionally built and stroked to 461 cu.in., churns out a commanding "496 hp and 573 lb-ft of torque." Utilizing the original 1967 Pontiac 400 Catalina engine as a base, it underwent extensive enhancements. The SD Performance-crafted hydraulic camshaft, ported #16 cylinder heads, and Rochester Quadrajet carburetor, alongside a revamped ignition system and cooling setup, ensure optimal performance and reliability.
