There were only 14 'Swiss Cheese' 1963 Pontiac Catalina 421 Super Duty cars produced. They had aluminum panels on the hood, trunk, fender, and bumpers. There were 120 holes punched in the side sections of the perimeter frame and the side of the box section was removed. This was the reason the car was given the name 'Swiss Cheese'. The lightweight construction and materials gave the car an overall weight of just 3308 lbs. The engine reportedly produced 420 horsepower but in reality produced well over 500.
This car was driven by such legendary names as Jim Wangers. It was raced out of Royal Pontiac Dealership in Royal Oak, Michigan. The car was campaigned nationally and was very successful. The biggest victory was at the U.S. Nationals when it won its class, beating out stiff competition. | |
