The article is wrong. the Fury V-800 was a dual 4bbl 318 only available in the Fury for 57/58. the dual 4bbl 350 Golden Commando was available in any plymouth for 1958.
Cool car, I love them Furys. Makes it extra special its from Wi. Mo, I hope you can find that car in HRM, love to see what the back window looks like. I recall the Inman Chrysler had a '60 ('61?) Comet back window.
1957 Virgil Exner had Ford and Chevy trying to figure out how they got caught with their Thong around their ankles. Mopar had the style and the motor and transmission to back it up. However, Mopar should have kept an eye on their assembly line workers not doing their job.
