Boat Marine Engine Bendix B175-34 Carburetor Flame Arrestor Chris Craft? 283 Bolt Set I can't find a partItem Details Not exactly sure what this came from as it was just loose in our supply of items. From my research it could have possibly been on something with a Chevy GM 283 engine as it seems like it's some sort of 4 barrel carburetor, but smaller than the ones typically found on rochester quadrajet carburetors.
