Looking at the picture, and seeing duel carbs. I don't think that an injection unit, it's just a butterfly hat and the box is not an intercooler, it's a filter box, The fake barrel valve is just a distribution block to the carbs. That's either a 671 or 871 blower, because the distributor is mounted in the back with no offset.
But it is a beautiful car.
