1975 Pontiac Grand Am - Grand Am Grand Slam
|
The 165 hp L65 400ci two-barrel was the standard Grand Am engine in '75, while the 185 hp L78 400 four-barrel and 200 hp L75 455 four-barrel were available at extra cost. A Turbo-400 automatic transmission and 2.56:1 rear axle ratio were the only choices that year. David opted for the L78, which added $50 to the final price. Directly beneath the original single-snorkel air cleaner is a No. 7045264 Rochester Quadrajet carburetor, and No. 496140 cast-iron intake manifold. The engine was repainted light-metallic blue like that used by Pontiac from '66-'70 during the restoration. View Related Article
