"Looks" like the carb that was on my 67 318 and 68 273, if that's any help.
Are there numbers stamped on the base plate? maybe if there are those would identify it.
This one is for my '66 Barracuda with the 273 engine. The number at the base is 1-1435 there is another number on the side of the float bowl that reads 0-1781 and another number at the back left corner of the carb which reads 6-1758
