I once owned a 1957 2 door sedan Chevy that was black with a white top that came from the factory with the Duntov Fuel Injection. The injection was later replaced with 3-2 bbls carbs. I sold it to a man (I think Lonnie was his name) that worked at the service station made of rock on the south side of the street going West bound. This was about 1966-67. If you have any info regarding this car please email me
