Brian - I'm not Jon "carbking", but I can offer some current pictures from what I know to the best of my knowledge is a 1953-58 Chevy 235 truck Rochester B that you can take a look at and try to figure out what you have.

My info on this being a '53-'58 truck 235 carb comes from this Rochester B Identification thread put together by Jon "carbking" and "John Milliman" (the Big Kahuna) to help Bolters figure out what they have. The PDF files attached to this thread must be downloaded to read as they won't open for some squirrely reason.

Hope this may help. wink
