For the 1965 model year, the GTO was once again a $295.90 option for the Pontiac Tempest/LeMans. The 1965 GTO had twin stacked headlamps replacing the side-by-side units of the 1964 model and a single center mounted hood scoop. Once again, the GTO was available in coupe, hardtop, and convertible models.
With a more aggressive camshaft profile and a revised intake manifold, the horsepower rating of the standard four barrel carbureted 389 V8 was bumped from 325 hp to 335 hp. The horsepower rating of the three two-barrel carbureted (Tri-Power) 389 V8 was raised to 360 hp. In August of 1965, Pontiac introduced a cold air induction kit for the Tri-Power GTOs, making the hood scoop functional with the purpose of feeding colder air to the engine.
