I have a 454 throttle body unit mounted on a transdapt carb manifold adaptor plate. The TBI unit has brand new stock injectors in it. and includes the adaptor for the IAC connector. The IAC adaptor allows you to hook up the newer style "flat 4" IAC to the older "square 4" wiring harness. I'll try to get a picture of this soon. Asking $225.00 plus shipping.
