Was that the one with certain Aluminum body parts?I know back in the sixties one of the most feared sleepers was the Pontiac Catalina 2+2 421 Super Duty with a four speed. 1962-1966. They'd pull 13.8 quarter miles and 3.9 second 0-60 times. Remember this was in a 4,400 pound car with skinny bias ply tires.
