1955 Chevy 6400,
You have a 1955 Second Series 6400, it looks all original with the correct Hood (same Hood is used on 1956), Hood Embelem and Fender Embelems. Go to the Gallery and look at other 55's and the 56/57's to see the difference.
As Spanky said, the 56 and 57 Hood Embelems are the same except they are painter in reverse to each other. The 56 has a Red bowtie and Black surround while 57 has a Black Bowtie with Red surround.
