When I was going to a lot of local shows about 10 years ago I used to see this guy from Grand Island, NY all the time. He had a 1971 black Cuda 440 six pack 4 speed car with a Power Bulge hood instead of a Shaker hood and tan interior. During one of our many conversations he said his car was the last documented 440 six pack Cuda ever made. Maybe he was referring only to 440 six pack cars but he was really into the hobby and I have no reason to not believe him.
