Re: Vintage Pontiac Pics
The 1963 Grand Prix X-400 show car. Pontiac built several X-400 cars over the previous years, the 1963 version had a fiberglass hood with dual hood scoops, which have a strange resemblance to the scoops used on the 1970 Buick GS years later. The engine was a supercharged 421, using a 4-71 blower, and 4 Corvette side-draft carbs. The exhaust system was built to allow the driver to control the exhaust gasses, with a 3-position bypass lever that allowed closed, partially open, and fully open exhaust. The exhaust pipes exited at the rocker panel in front of the rear wheelwells.
