You will need:
- TB
- TB-UIM gasket
- throttle cable bracket
- new accelerator cable
- larger accordian tube (I used a BAT pipe - works and looks better anyway)
Hope this helps! 
Actually, that isn't entirely true. I machined my stock upper intake manifold at the inlet to port match my ported and polished SVT TB. It also makes quite the difference in performance. Well worth the money, but I highly recommend machining the inlet on the upper to mate properly.
