Yeah, I can't really make heads nor tails of it. The belt driven acc looks a lot like a Bendix vacuum pump, but it has too many hoses on it. 
 My recollection is the early Fab's would have an updraft carb, but I could be wrong. Too much we can't see.

The intake tube to the carburetor seems to be connected to the top of the rocker cover which seems odd.

Two of the ducts are going into the cab. It may be some kind of heater. It really seems more like air conditioning. But it seems too early for A/C, although Packard had it in 1940.

Hard to tell from the pic's the engine is the stock FAB 6, early version with the distributor on the back of the genny. It might be a belt driven supercharger (vane type blower) but hard to see enough of what was going on with all those tubes. 

What are they showing off here ?

I've seen a lot of pictures of those 400's but none recent or at any shows.  I wonder if any survived?

This was posted online long ago. I don't know anything else about it.
