For example, here is the same exact throttle body (even has the same pictures) for $108 less.

Accel, FAST, Edelbrock, and Acufab all sell 4150 TBs for less than $450-$500, so it seems odd you were looking at an ebay unit that was more than $400 bucks.
Here is one from BBK for $400, http://www.ebay.com/itm/BBK-1000CFM-4-BARREL-THROTTLE-BODY-FITS-1-3-4-BORES-CARB-INTAKE-MANIFOLDS-1716-/380608887401?pt=Motors_Car_Truck_Parts_Accessories&hash=item589e0eba69&vxp=mtr.
