I have an '83 with a 351. From what I understand, they put different power plants in the boats, including the Chrysler. My guess (and I'm hoping someone can chime in with more facts) is that when they became short on engines, they filled the boats with the Chryslers.
With a 440, that things gotta go like a bat otta h3ll. Definitely a rare find. Post pics when you have them.
Hello, my name Ryan!
