1953 Chevy Truck...

but the engine is a 55-57 block... (the many juries around the net
are still out on if it is a 235 or 261)

so...

on the tag, which I have read is not a part number, but
an "application tag" it has this:

7013029

B8 39(the 39 is rotated 90 degrees)

on the side of the body of the carb:

Rochester

GM carburetor

made in the usa

patents appld for

-----

on the very bottom of the carb, that part that would be mounted to
the intake... this number appears:

130290 ( I'm pretty sure the 1 is a one, or a REALLY straight scratch)

at the bottom of the carb, but on the side is this number:

4522 and nearby is the number 37

and vertically... is the number 036 on the body.
