340 2 barrel manifold

I was asking because I found a small block with factory orange paint and valve covers,its never been apart or messed with,it was removed from a brand new car back in the day,but it's only got a 2 barrel manifold,could it have been a special order?
You should look at the numbers on the side of the block. None of us have seen or know about a 340-2 barrel. Never say never with Mopar but very highly unlikely.
