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.

I would have liked it more ( still would not put it on) if it were painted same color as the car. Chrome, WTH was he thinking????????????????
Was he trying to balance the rear with some chrome to match the front with the chrome on the motor?
