OK - I have located a decent blower setup for my Y that is on the engine test stand, looking to debut this setup at the end of July in Somerset, PA - just for fun on the trailer.
You got to love tradin'. The fella I got this from swears up and down that this set up was on a Y block. Here is the crank pulley, but no number anywhere, and it has an obvious repair. Someone did balance the thing, or tried too at least...
And here is the bracket that holds the blower. For the life of me, I could not tell during mock up which way this thing is supposed to sit. It looks as if the two bolt holes are the exact same width apart as the water pump holes are,,,but I keep thinking that this looks like a passenger side bracket, not a drivers side bracket (take a look below at the airbox)...
The tensioner arm number is 37603 and F-20940.
The airbox...
Inside the airbox is a nice little Bendix Stromberg 4 bolt carburetor with Model WW. Isn't this a Studebaker box? Could this be adapted to a Y? The blower that came with the setup says McCulloch Supercharger on the plate, not Studebaker.
Now the for two UFO's 
I have no cotton-pickin' idea what these little doohickeys are. They are metal discs about 2 inches across or so. The bolts are just loose through the middle connected to a nut. Ideas?
One small bracket...
Once the blower bracket is oriented correctly, I am sure that this will come into view also.
I searched the VS57 website pretty closely. Did find the airbox, but no diagrams or good photos of the bracket and how it should bolt to the Y. Anybody running this set up and have a decent looking photo to shoot back at me?
