Ok, I have to ask, since this topic is really peaking my interest.

What did the stock 3.8's that these were on have done to them to allow for boost? were they just cast pistons, since it was a relatively low boost situation, or...?

I know those blown 3.8s really went...an ex gf had one. miss the car, not her...haha..

Also, would it be possible to mount the blower 90 deg., with the bottom facing in the ports, and "stagger", i guess, the pulleys like it was mentioned ford did? And would this be an acceptable way to acheive even air/fuel flow within the plenum to the ports?
