|Pontiac Grand Prix 1967|
Revised sheetmetal with more rounded wasp-waisted styling highlighted the 1967 Grand Prix and other full-sized Pontiacs, along with the addition of a new Grand Prix convertible. Also new to the GP were concealed headlights with horizontal mounting (all other full-size '67 Pontiacs retained the vertical headlights for one more year), concealed windshield wipers and ventless front windows on hardtop coupes. Out back were louvered taillights similar to those found on the GTO.Inside, Strato bucket seats and console were still standard equipment with Morrokide vinyl or cloth upholstery, or a no-cost optional notchback bench seat with either trims. Other changes included a revised instrument panel and door panel trim.Under the hood, the 389 V8 was replaced by a new 400 cu in (6.6 l) V8 with four-barrel carburetor, dual exhausts and 350 hp (260 kW). Similarly, the 421 V8 was replaced by a new 428 cu in (7.0 l) V8 rated at 360 hp (270 kW) or an HO version with 376 hp (280 kW) - both with four-barrel carburetors. Both the 400 and 428 V8s were basically bored out versions of the older 389/421 block but with various internal improvements including bigger valves and improved breathing capabilities.
