Hi all, I recently bought this intake to use on a 'cuda street car. I was told it was an original A12 intake but after researching it a little, this does not have the slanted, or lazy "6" at the end of the part number. It also does not have the CH6B in the center of the drivers side. So, some say if the CH6B is missing it is original; and some say it must have the slanted "6" to be original. So what do you all think I have? It doesn't matter to me as I don't have an original A12 car, I'm just curious. I will be using it with an original factory set of 340 + 6 carbs on the 440.
