1965 Pontiac Grand Prix

The Pontiac Grand Prix, which was introduced with the 1962 model, was based on the Catalina model. The Grand Prix was a sportier looking Catalina with a luxurious interior.

The first generation Grand Prix ran from 1962 through the 1968 model year. First generation models were full size vehicles and became mid sized starting with the second to the fifth generation for the sedan and to the sixth generation for the coupe.

1965 Pontiac Grand Prix Styling

Both the 1965 and 1966 Grand Prix (few changes from 65 to 66) are noted for it’s flowing appearance, kicked up rear fenders and quad headlights. The 1964 models had much more straight lined styling. Interiors were also restyled with an all new instrument panel. The 1965 Pontiac Grand Prix was also a weightier car with a longer wheelbase and the 65 models in general used chrome sparingly which you can readily see with our featured model. You will also note that the 65 model used plenty of sheet metal.

Another thing the second generation had going for it was it’s power. Engines for the 1965 Grand Prix included a 389 and 421 cubic inch V-8 with varying configurations and horsepower output.

Pontiac Tri-Power

On select models from 1957 through 1966 General Motors offered  Pontiac’s Tri-Power induction system. This turned out to be a popular addition to the muscle car era that included a factory triple-carburetor system. These were three Rochester two-barrel carburetors. This was offered on 347, 370, 389, and 421 cubic inch engines.

Rather than having a fuel injection system which was considered pricey, GM added carburetors to beef up performance. Hot rodders had been doing this for some time and Pontiac decided to do the same. The entire Tri-Power addition cost about $100. Performance was similar to the fuel injection set up but cost much less.

Three carburetors under the hood packed plenty of punch and gave Pontiac a great marketing advantage in an era of muscle cars.
