The 1967 Pontiac GTO was again a full-fledged model instead of just an option package of the Tempest/LeMans and its appearance is very similar to the 1966 GTO. A new plastic grille, rocker moldings (including the relocated “GTO 6.5 Litre” emblem), and the taillamps are the most noticeable exterior differences between the 1966 and 1967 GTOs. Two new exterior options were introduced in 1967: A hood-mounted tachometer and the Rally II wheels. Again, the GTO had the signature Pontiac stacked headlamps and split front grille and was available in coupe, hardtop, and convertible models.
The biggest change between the 1967 GTO and the 1966 is under the hood. A 400 cubic inch engine replaced the 389 from the previous years and the famous “Tri-Power” carburetion was no longer an option. (Note: Despite the increase in cubic inches, Pontiac kept the GTO’s familiar 6.5 Litre emblems) The base engine for the 1967 GTO was a four barrel carbureted 400 rated at 335 hp. The optional four barrel carbureted 400 HO (for High Output) was rated at 360 hp. Header type exhaust manifolds, a hotter cam, and an open-element air cleaner contributed to the extra power. The cold air induction “Ram Air” kit making the center-mounted hood scoop functional could be ordered for the HO. A no-cost option two-barrel carbureted 400 (available only with an automatic transmission) was available for folks who wanted a GTO but not the added gasoline and insurance expenses that came with the higher performance engines.
